Columns

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
plate_id	int	meta.id		Plate identification number
archive_id	int	meta.id		Archive identification number
solution_num	short	meta.number		Solution number in the solution set
iteration	short	meta.record		Iteration number
color_term	float	stat.fit.param		Color term of the plate, characterizing color response of the emulsion and filter used
color_term_error	float
cterm_stdev_fit	float
cterm_stdev_min	float
num_calib_stars	int	meta.number		Number of stars that were actually used for photometric calibration in the annular bin
cterm_range_min	float
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.
cterm_range_max	float

bright_limit	float	phot.mag em.opt stat.min	mag	Brightest source magnitude among calibration stars, belonging to the current astrometric solution, in the plate natural photometric system
cterm_iterations	short
cterm_num_stars	int
faint_limit	float	phot.mag em.opt stat.max	mag	Estimated faint limit of the current astrometric solution in the plate natural photometric system
mag_range	float	phot.mag em.opt arith.diff	mag	Magnitude range between the bright and faint limit
num_gaia_edr3	int
num_candidate_stars	int
rmse_min	float	stat.error phot.mag em.opt stat.min	mag	Minimum root-mean-square (RMS) error estimate for magnitudes in the plate natural photometric system
rmse_median	float	stat.error phot.mag em.opt stat.median	mag	Median root-mean-square (RMS) error estimate for magnitudes in the plate natural photometric system
rmse_max	float	stat.error phot.mag em.opt stat.max	mag	Maximum root-mean-square (RMS) error estimate for magnitudes in the plate natural photometric system
timestamp_insert	char	time.creation	Time[yyyy-mm-dd hh:mm:ss]	Timestamp of insert
