PDCS fan, The files in this directory contain the galaxy catalogs from which the PDCS was derived. *hr_V_pdcs_pub.cat.gz = gzipped catalog with data for V band *hr_I_pdcs_pub.cat.gz = gzipped catalog with data for I band *.exclude = exclusion regions (xmin,xmax,ymin,ymax) where limits are for Global X/Y positions (see below) The file names all begin with the 2 digits of the R.A. hour of the PDCS field. All files are ascii files (when uncompressed!). See Postman et al. 1996, AJ, 111, 615 for details about how the catalogs were created. The following data are in each column of the *pdcs_pub.cat files: Column # Parameter 1 J2000 Right Ascension (Hours) 2 J2000 Right Ascension (Minutes) 3 J2000 Right Ascension (Seconds) 4 J2000 Declination (Degrees) 5 J2000 Declination (Minutes) 6 J2000 Declination (Seconds) 7 Global X position (1 unit = 0.335 arcsec) 8 Global Y position (1 unit = 0.335 arcsec) 9 Isophotal magnitude 10 Total magnitude 11 Classification (1 = star, 2 = galaxy) The catalogs have been filtered to exclude objects in known areas around bright stars or where data is unreliable for other reasons. Magnitudes HAVE been corrected for Galactic extinction with the following corrections: Field A(V4) A(I4) --------------------------------- 00h 0.055 0.027 02h 0.028 0.014 09h 0.004 0.002 13h 0.031 0.015 16h 0.019 0.009 --------------------------------- I band data provided down to extinction corrected limit of I=22.45 V band data provided down to extinction corrected limit of V=23.75
