Galaxy List (Not used in Generic SAS)

Filename: specified by config.dat

Lists all the galaxies that you want to analyze.  Must be 2 lines per galaxy, of the form:

12  36  17.600  62  14  2.20  0.818  E  4  21.73  F 
   36.93  0.91  0.68  0.27  4500.0

On the first line, the first six numbers are the coordinates, followed by the redshift, the galaxy spectral class, the redshift quality class, the R magnitude, and the location indicator (F = flanking fields, H = HDF, O = outside).  The second line is not used in the program but is necessary for the file to be read correctly.

This list can be as long as you would like, but be aware that SAS will automatically analyze every galaxy on this list without prompting the user, so increasing list size directly increases the time it takes to run the program.

Redshift List (Used only in Generic SAS)

Filename: specified by config.dat

Lists all the spectrum filenames and their associated redshifts.  Must be 1 line per spectrum, and can be of the any of the forms:

mygalaxy.list             0.987
mygalaxy.fits             0.789
MYGALAXY.FITS.REDSHIFT    0.256

Generic SAS attempts to match up the portion of the filename in the redshift list up until the first period (".") with the list files in the spectra directory, so what is included after the first period is ignored.  Case is also ignored.

This list can be as long as you would like, but be aware that SAS will automatically analyze every galaxy on this list without prompting the user, so increasing list size directly increases the time it takes to run the program.

 Feature List

Filename: specified by config.dat

Lists the features you want to analyze in the galactic spectra.  Must be 2 lines per feature, of the form:

For emission/absorption lines, the first line of the feature list must be in the order {line wavelength, low continuum starting wavelength, low continuum ending wavelength, high continuum starting wavelength, high continuum ending wavelength, number of pixels on either side of line to include in the feature analysis} and formatted as above.  The second line is a string that describes the feature.

For breaks/discontinuities, the first line of the feature list must be in the order {low continuum starting wavelength, low continuum ending wavelength, high continuum starting wavelength, high continuum ending wavelength} and formatted as above.  The second line is a string that describes the feature.

There is no need to put the break and lines in any special order in the feature file.  SAS will automatically recognize whether the feature is a line or a discontinuity based upon the number of wavelengths listed in the first line of the feature entry.  However, you should note that the output data files will contain the features in the same order that you input them in the feature list.

Airmass List

Filename: specified by config.dat

Contains the list of airmasses for each spectrum file.  Must be of the form:

F36109X1510_96M3.FITS.AIRMASS Double 1.42

It does not matter what order the airmasses are in relation to the galaxy list or the exposure time list.  SAS searches for the filenames.

Exposure Time List

Filename: specified by config.dat

Contains the list of exposure times for each spectrum file.  Must be of the form:

F36109X1510_96M3.FITS.ELAPTIME Float 3000

It does not matter what order the exposure times are in relation to the galaxy list or the airmass list.  SAS searches for the filenames.

Night Sky Lines List

Filename: specified by config.dat

Contains the night sky lines that will be erased from the spectra.  Must be of the form:

5577.0
6300.0
7590.0
7660.0

With each wavelength on its own line.

Response Functions

Filenames: specified by config.dat (recommended - resp150.list, resp300.list, resp400.list, and resp600.list)
Directory: spectra directory

These are the *.dst response functions converted to *.list files by slist.  They should have exactly the above filenames and should be placed in the list directory along with the spectra.

Extinction Corrections

Filenames: specified by config.dat (recommended - ext150.list, ext300.list, est400.list, and ext600.list)
Directory: spectra directory

These are the *.dst atmospheric extinction corrections converted to *.list files by slist.  They should have exactly the above filenames and should be placed in the list directory along with the spectra.
