Description |
| PHOTOMETRIC |
0 |
Photometric observations |
| UNPHOT_OVERLAP |
1 |
Unphotometric observations, calibrated based on overlaps with clear, ubercalibrated data; done on a field-by-field basis. Use with caution. |
| UNPHOT_EXTRAP_CLEAR |
2 |
Extrapolate the solution from the clear part of a night (that was ubercalibrated) to the cloudy part. Not recommended for use. |
| UNPHOT_EXTRAP_CLOUDY |
3 |
Extrapolate the solution from a cloudy part of the night (where there is overlap) to a region of no overlap. Not recommended for use. |
| UNPHOT_DISJOINT |
4 |
Data is disjoint from the rest of the survey (even though conditions may be photometric), the calibration is suspect. Not recommended for use. |
| INCREMENT_CALIB |
5 |
Incrementally calibrated by considering overlaps with ubercalibrated data |
