Archives of Photographic PLates for Astronomical USE

Photometric color term (applause_dr2.phot_color)

The table has 36483 rows, 16 columns.

Description

Color term of a photographic plate was determined by fitting a photometric calibration curve with a range of trial color term values. The lowest standard deviation of residuals corresponds to the color term of the plate. This table contains data on the determined color terms. Each row in the table corresponds to a scan of a photographic plate. Unique Identifier color_id
