# Photometric calibration of APM POSS-I plates derived using APS photometry # # From McMahon, White, Helfand & Becker, 2001, "Optical Counterparts for 70,000 Radio # Sources: APM Identifications for the FIRST Radio Survey", ApJSupp, in press # # Description of columns: # # Pl Running plate number (note this is not necessarily consecutive) # Plate Name of POSS-I plate # Nobj Number of objects used to calibrate this plate # E0,E1,E2 Coefficients for E (red) magnitude correction. The corrected # magnitude is Ecorr = E0 + Eorig*(E1 + Eorig*E2), where # Eorig is the uncalibrated APM catalog magnitude. # O0,O1,O2 Coefficients for O (blue) magnitude correction. # dE(17.5) Size of magnitude correction at (original) E = 17.5 # Flg '*' indicates that objects from overlapping APM plates were used # instead of APS to calibrate this plate (see paper for details.) # #Pl Plate Nobj E0
