| name | value | description |
| PHOTOMETRIC | 0x0001 | Photometric data that was ubercalibrated |
| UNPHOT_OVERLAP | 0x0002 | Calibrate based on overlaps with clear, ubercalibrated data; this is done on a field-by-field basis |
| UNPHOT_EXTRAP_CLEAR | 0x0004 | Extrapolate the solution from the clear part of a night (that was ubercalibrated) to the cloudy part |
| UNPHOT_EXTRAP_CLOUDY | 0x0008 | The solution here is based on fitting the a-term to cloudy data. |
| UNPHOT_DISJOINT | 0x0010 | Data is disjoint from the rest of the survey (even though conditions may be photometric), the calibration is suspect |
| INCREMENT_CALIB | 0x0020 | Incrementally calibrated by considering overlaps with ubercalibrated data |
| RESERVED2 | 0x0040 | Reserved for future use |
| RESERVED3 | 0x0080 | Reserved for future use |
| PT_CLEAR | 0x0100 | [Internal use only] PT calibration for clear data |
| PT_CLOUDY | 0x0200 | [Internal use only] PT calibration for cloudy data |
| DEFAULT | 0x0400 | [Internal use only] A default calibration is applied (no PT or ubercal) |
| NO_UBERCAL | 0x0800 | These data are not uber-calibrated. |
