Faint Sky Variablity Survey (FSVS) ---------------------------------- Contact: Steve Howell , Mark Huber A description of the photometry .final files. --------------------------------------------- The astrometry/photometry catalogs are in the format F_NN_CCD#.finalN where NN is the field number (see Groot et al. 2003, MNRAS,) and # is the CCD number from 1-4 in the WFC instrument. The N designates the type of photometry for the V light curve as described below -- final.N Dataset Type 1 variable PSF fitting magnitude 2 fixed 12 pixel aperture magnitude 3 isophotal magnitude 4 2xFWHM aperture magnitude** **All B and I magnitudes are from this aperture. The catalog .final files are divided into 2 sections, a header and date section. The header section starts with line 1-Nobs+5, where Nobs is the number of observations given by Nobs = |(Ncol-16)/5|. The "-" indicates the data has been astrometrically and photometrically processed. The number of sources is the |Nrow| value. The data section then starts at line Nobs+8 and continues to line Nrow+8.
