VizieR Online Data Catalog: Palomar Transient Factory (PTF) photometric catalog 1.0 (Ofek+, 2012)

The Palomar Transient Factory (PTF) is a synoptic survey designed to explore the transient sky and to study stellar variability. The project utilizes the 48-inch Samuel Oschin Schmidt Telescope at Palomar Observatory. The telescope has a digital camera equipped with 11 active CCDs, each 2Kx4K pixels, and has been surveying the northern sky since March 2009. Each PTF image covers 7.26 deg² with a pixel scale of 1.01arcsec/pix. The median point-spread function FWHM is about 2arcsec and it is uniform over the camera field of view.

The PTF main survey is currently performed in the g-band during dark time and in the Mould R-band (close to r-band) toduring bright time, but most of the data taken prior to January 2011 were obtained using the R-band filter. In addition, a few nights around times of full Moon are used for surveying the sky with narrow-band Hα filters.
