Photometric calibration: color term estimation (applause_dr3.phot_cterm)
The table has 7512406 rows, 12 columns.
Description
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
