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 em.opt stat.min |
mag |
Brightest source magnitude in the plate natural photometric system in the annular bin |
| faint_limit | float |
phot.mag em.opt stat.max |
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 phot.mag em.opt stat.min |
mag |
Minimum root-mean-square (RMS) error estimate for magnitudes in the plate natural photometric system in the annular bin |
| 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 annular bin |
| 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 annular bin |
| timestamp_insert | char | time.creation | Time[yyyy-mm-dd hh:mm:ss] |
Timestamp of insert |
| timestamp_update | char | time.creation | Time[yyyy-mm-dd hh:mm:ss] |
Timestamp of last update |
