Name Type UCD Unit Description
calib_id int meta.id
meta.main
Calibration identification number
process_id int meta.id Process identification number
scan_id int meta.id Scan identification number
exposure_id int meta.id Exposure identification number
plate_id int meta.id Plate identification number
archive_id int meta.id Archive identification number
annular_bin short meta.code Annular bin (1-9) where the source belongs (bin 1 is in the center, bin 9 is at the edge)
color_term float stat.fit.param Color term of the plate, characterizing color response of the emulsion and filter used
color_term_err float stat.error
stat.fit.param
Error on color term of the plate
num_bin_stars int meta.number Number of stars in the annular bin in which photometric calibration was carried out
num_calib_stars int meta.number Number of stars that were actually used for photometric calibration in the annular bin
num_bright_stars int meta.number Number of bright stars that were actually used for photometric calibration in the annular bin. Bright-star calibration was handled separately and then merged with the calibration curve.
num_outliers int meta.number Number of stars that were found to be outliers of the photometric calibration curve in the annular bin
