The PTF Project
The program is centered on a 12Kx8K, 7.8 square degree CCD array (CFH12K) re-engineered for the
1.2-m Oschin Telescope at Palomar Observatory by COO (Rahmer et al. 2008). Photometric
followup is undertaken by the automated Palomar 1.5-m telescope (Cenko et al. 2006) and other
facilities provided by consortium members.
PTF uses eighty percent of the 1.2-m and fifty percent of the 1.5-m telescope time. With an exposure of 60-s the survey reaches an approximate depth of m_R=20.5 and m_g'=21.
Two major transient detection experiments are planned for the five-year project:
1) a 5-day cadence supernova search
2) an exotic transient search with cadences between 90 seconds and 1 day.
PTF provides automatic, realtime transient classification and followup, as well as a database including every source detected in each frame.
PTF is a collaboration of Caltech, LBNL, IPAC, Berkeley, LCOGT, Oxford, Columbia and the Weizmann Institute.
