Columns

Name	Type	UCD	Unit	Description
sub_id	int	meta.id meta.main		Unique sub-field 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
phot_sub_grid	short	meta.number		Grid level for the current sub-field, expressed as the number of divisions of an image in one axis. Possible values: 2, 4, 8, 16, 32.
phot_sub_id	int	meta.id		Hierarchical sub-field number, characterising the size and location of the sub-field in the image. 1 - lower left, 2 - lower right, 3 - top left, 4 - top right. First level (grid 2): 1, 2, 3, 4; second level (grid 4): 11, 12, 13, 14, 21, 22, ..., 44; third level (grid 8): 111, 112, 113, 114, 121, 122, ..., 444; fourth level (grid 16): 1111, 1112, ..., 4444; fifth level (grid 32): 11111, 11112, ..., 44444.
parent_sub_id	int	meta.id		Hierarchical sub-field number for the parent sub-field (0 for grid level 2). Example: for sub-field 2134, the parent sub-field is 213.
x_min	float	pos.cartesian.x stat.min		X-coordinate of the left edge of the sub-field
x_max	float	pos.cartesian.x stat.max		X-coordinate of the right edge of the sub-field
y_min	float	pos.cartesian.y stat.min		Y-coordinate of the bottom edge of the sub-field
y_max	float	pos.cartesian.y stat.max		Y-coordinate of the top edge of the sub-field
num_selected_stars	int	meta.number		Number of selected stars for improving photometric calibration in the sub-field
above_threshold	short	meta.code		1 if the number of selected stars is above threshold (50) for improving photometric calibration in the subfield, 0 otherwise
num_fit_stars	int	meta.number		Number of stars actually used for improving photometric calibration in the sub-field (remaining after sigma clipping)
correction_min	float	phot.mag phot.calib stat.min	mag	Minimum magnitude correction that was applied in the current sub-field
correction_max	float	phot.mag phot.calib stat.max	mag	Maximum magnitude correction that was applied in the current sub-field

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 in the sub-field
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 in the sub-field
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 in the sub-field
