Call for Proposals 2015A
Proposals Due by 6:00 pm PDT Wednesday 01 October 2014
This call is closed and provided for reference only
- Keck I and Keck II, with possible trades for SUBARU time.
- Palomar 200-inch.
- Palomar 60-inch (service observing only).
- Palomar Oschin Telescope (service observing only).
Caltech Faculty, Senior Research Associates, Senior Research Fellows,
Post-Doctoral Scholars, Senior Research Staff (approved by the COO Director) and Graduate Students may
apply for COO-administered observing time at Keck and Palomar, subject to the following:
- Applicants must be in residence at Caltech at the time proposals are submitted.
- Caltech Faculty and Senior Research Associates may submit no more than three Keck proposals
and/or any number of Palomar proposals.
- Caltech Senior Research Fellows, Post-Doctoral Scholars and Senior Research Staff may submit any number
of Palomar proposals but are limited to one Keck proposal per semester.
- Caltech Graduate Students may apply for Palomar time only.
- Each proposal should cover a single, coherent, well-defined scientific topic.
- If two or more Keck proposals are submitted, the one representing your highest-priority should be designated
as Priority 1 or Principal; all others are Priority 2 or Secondary. Similarly, if
two or more proposals are submitted for the Palomar telescopes, your highest priority project should be designated
as Principal and all others as Secondary. Only one proposal for Keck time and only one proposal for
200-inch time may be designated as Principal. Proposal Principal/Secondary designations are made on the Keck and Palomar
coversheets -- please make your priority intent clear for time allocation processing, and please note that
different Principal/Secondary page limits apply (see below).
- Proposals consist of four parts: Cover Sheet, Discussion, Figures, Observing List.
- Cover Sheets:
Discussion: Provide a short (see page limits, below) description of the project, explaining
the scientific goals and methodology, and justifying the time and equipment requested. Also include citations
to publications referenced in the discussion. For new projects, provide an estimate of the total time
required to complete the work; for continuing projects, give the status of previously obtained data and an
estimate of the time needed to finish. For projects in support of an approved thesis, include an estimate
of the total observing time required, the time already allocated and the status of the data already in hand.
Explain any constraints that may affect scheduling.
Figures: Collect all images, graphs, tables, etc. into a single section. N.B. Copies of the
proposals sent to the TAC members will be printed in black-and-white format but the committee members will
be able to access color versions in a secure on-line directory.
Observing List: Provide a list of targets to be observed, including names, coordinates and
Page limits: 1 page = One side of a sheet 8½ x 11 inches, with suitable margins.
Type size = 11- or 12-point.
- Keck: Follow the procedures at
Applying for Keck Telescope Time. Keck uses an on-line system with password protection to
allow observers to retrieve and modify their cover sheets. If you are a returning observer, use the
same account information as in previous semesters. If you are a new observer, request an account by
following the instructions on the log-in page.
- Palomar: Please use the appropriate cover sheet
When finished, combine your cover sheet with the Discussion, Figures and Observing List into a single pdf document
(see note below). Check that the file is smaller that 1M and attach it to an e-mail
not later than 6:00 pm PDT Wednesday 01 October 2014. The subject line of the message should be
in the following form: [your last name]-[Telescope]-[A sequence number to distinquish it from others others submitted for
the same telescope]. Examples: Jones-Keck-1 or Jones-P200-2.
|Principal Proposal ||3 pages ||4 pages ||As needed|
|Secondary Proposals ||2 pages ||4 pages ||As needed|
|Palomar - Large Project ||8 pages ||4 pages ||As needed|
- For projects requiring date-specific scheduling: (a) Be sure to check the appropriate box on the cover sheet and
(b) include in the Figures section of the proposal a table of the events to be observed. Give the name
of the object, its coordinates, and the date and time (Pacific Time for Palomar, Hawaii Time for Keck) of the event.
[Remember: Telescope time to observe an event occurring - for example - at 02h PDT on 6 August has to be scheduled
for the night of 5 August.]
- For projects involving both Keck and Palomar, submit the Keck and Palomar cover sheets
separately. The discussion, figures and observing list need only be attached to the Keck
- Requests for half nights will be accommodated within the constraints set by the scheduling. When
requesting half nights, specify in the proposal discussion whether first-half or second-half time
- Target of Opportunity projects may be requested for Keck and/or the 200-inch. See
- For Keck instrument availability in 2015A, go to
Keck Instrument Availability.
- Only a single proposal (cover sheet, discussion, figures and observing list) is needed for a project
involving both Keck I and Keck II.
- LGS observing at Keck is critically dependent on conditions and you are advised to have a
contingency plan should LGS be unavailable. See
Policy on Backup
Instruments During LGS-AO Runs.
- NIRC2 will have a 3 to 5 week service mission beginning in mid-February and will not be available during
- DEIMOS will begin a service mission in January 2015, with completion expected in mid-February 2015. The plan
is to have DEIMOS available for the February dark run beginning on 14 February.
- AO Upgrades: On Keck I: The new near-IR tip/tilt system, TRICK, is being commissioned in 2014B and
probably will be available on a Shared-Risk basis during 2015A. Proposals should not rely on its
availability, however. On Keck II, the new Center-launch Laser System, CLS, is expected to be activated
sometime during the 2014B semester, providing the Keck II AO system with a smaller laser spot size.
- A limited amount of Keck time may be traded for time at SUBARU in 2015A. Subaru will offer: Suprime-Cam [dark
runs in February, April and June]; FOCAS; HDS; MOIRCS (possible limited availability); IRCS (with NGS/LGSAO188
elements); FMOS; COMICS; Hyper Suprime-Cam [Shared-Risk basis, 3 nights maximum for all Keck users,
dark runs in March, May and July].
- NIRES may be available for science observing on Keck II in 2015A on a Share-Risk basis. Proposals
calling for its use, however, must include in the Discussion a section entitled Back-up Program
naming the substitute instrument (either NIRSPEC or NIRC2-NGS) to be used should NIRES be unavailable. If
the back-up program differs substatially from the main-line proposal, briefly describe its scientific goals
and add a list of the back-up targets to be observed.
- For projects involving more than one Palomar telescope, submit the appropriate cover sheet for each
separately. The discussion, figures and observing list need only be attached to
the cover sheet for the larger telescope.
- For Hale Telescope instruments, see the table below. Private and Semi-private
instruments may be requested only with the prior approval of the instrument builder.
- DBSP, LFC, WIRC and TripleSpec may be operated by remote observing. For additional information, see
- The Palm 3000 system (P3K) will be in regular operational status with the PHARO facility near-IR camera
in 2015A. P3K will remain on Shared-Risk status with the SWIFT instrument. Interested proposers
should see the 200-inch Instrument Table below, and the
P3K Observers information
- P3K and the East Arm Echelle cannot be scheduled simultaneously (issues with telescope balance).
- Observers using the 200-inch telescope may request instruments to be installed simultaneously at the prime
focus, Cassegrain focus and/or the east-arm focus (East Arm Echelle only).
The use of a secondary instrument must be identified on the cover sheet and
justified in the proposal discussion. On the Cover Sheet, select the principal instrument to be used from
the drop-down lists on the Observing Time Preferences table and specify the secondary instrument in
the space provided under Additional Information. Secondary instruments should be requested only
if they are integral to the program and if there is a very high probability that they
will be used during the observing run.
- Proposals for 200-inch time in support of Large Projects may be submitted. See
Proposals for details.
- Palomar 60-inch Telescope - Up to 20% of the time at the 60-inch may be allocated to
Caltech observers for general research. Please see
P60 Observers Information
for information on planning P60 observations.
In addition to the facility CCD camera,
the Robo-AO high-resolution imaging system will be offered on a
semi-private basis (interested proposers must contact Reed Riddle email@example.com).
Both the P60 facility camera (CCD Cam) and Robo-AO operate only
in service observing mode. Caltech observers may request observing time using the SED Machine, which will be
available on a Shared-Risk basis.
- Oschin (P48) Telescope - Up to 20% of the time at the Oschin/P48 Telescope
(with the MOSAIC camera) may be allocated to Caltech observers for general research.
P48 Observers Information
for information on planning P48 observations. Note P48 operates in service observing only.
Note on Merging PDF Documents
To combine the cover sheet and discussion section of a proposal, use the full version of Acrobat (Acrobat Reader will not work) or the joinpdf program on the AY Unix computers. Also see www.astro.caltech.edu/palomar/mergepdf.html.
Proposal pdf documents are typically 500K to 1M in size. Files larger than 1M are cumbersome
to handle, so, if your proposal is larger than 1M, please try reducing the resolution of your images.
Observing History and Bibliography
The Director and the Time Allocation Committee place a high premium on the effective use
of telescope time and the prompt publication of results derived from the observations. Accordingly, your report
accounting for your previous observing time and your publications constitutes an important adjunct to your
proposals. Submit this report as a single, two-part document consisting of:
- Observing History: List the observing time allocated to you for all projects in the last eight semesters
[2011A to 2014B, inclusive] and summarize the status of each. Provide:
Bibliography: Provide a bibliography of your refereed papers based on Keck (or from observing time awarded
through Keck trades) and/or Palomar data, published or submitted for publication during the last eight
semesters [2011A to 2014B, inclusive], even if you were not the principal investigator of the observing proposals.
- Telescope and proposal number.
- Instrument(s) used.
- Number of nights allocated and the number of nights useable.
- For ToO projects, give a comprehensive list of the interrupts invoked, including for each the date, telescope, instrument and duration.
Attach the report (as a pdf document) to an e-mail to firstname.lastname@example.org (not later than 6:00 pm PDT
Wednesday 01 October 2014 with the subject line in the following form: [your last name]-History. (For example: Jones-History)
Submit this report as a completely separate document. Do not include it in your proposal(s).
Instrumentation for the Keck Telescopes is summarized on the
WMKO Keck Instrument Page.
200-inch Telescope Instruments
Instrumentation for P200 is summarized on the
P200 Instrument Page.
If you propose to bring your own equipment to P200 please specify the
appropriate focus code [Prime Focus (OE-PF), Cassegrain (OE-Cass),
Cassegrain + P3K Base (OE-Cass+P3K), or Coudé (OE-Coudé)] on your
