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

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) on the scanned photographic plate (bin 1 is in the center, bin 9 is at the edge). Bin 0 refers to the whole image.

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

bright_limit float phot.mag

stat.min
mag

mag

Faintest source magnitude in the plate natural photometric system in the annular bin

mag_range float phot.mag
em.opt
arith.diff
mag

Magnitude range between the brightest and faintest source magnitudes in the plate natural photometric system in the annular bin

rmse_min float stat.error

stat.median
mag

Median root-mean-square (RMS) error estimate for magnitudes in the plate natural photometric system in the annular bin

rmse_max float stat.error
phot.mag
