Fitting parameters for photometric calibration (applause_dr2.phot_cterm)

The table has 4344071 rows, 12 columns.


Fitting parameters for photometric calibration.The color term of a photographic plate was determined by fitting a photometric calibration curve with a range of trial color term values. Each fit leaves magnitude residuals. This table contains standard deviations of residuals for each fit. Unique Identifier cterm_id
