| Name | Type | Description | Notes |
|---|---|---|---|
| instrument_id | int | ID of the instrument with which the observation was carried out. | |
| filter | str | The bandpass of the observation. | |
| fluxerr | float | Gaussian error on the flux in counts. | |
| mjd | float | MJD of the observation. | |
| zp | float | Magnitude zeropoint, given by `ZP` in the equation m = -2.5 log10(flux) + `ZP`. m is the magnitude of the object in the magnitude system `magsys`. | |
| obj_id | str | ID of the Object to which the photometry will be attached. | |
| magsys | str | The magnitude system to which the flux and the zeropoint are tied. | |
| ra | float, none_type | ICRS Right Ascension of the centroid of the photometric aperture [deg]. | [optional] |
| dec_unc | float, none_type | Uncertainty on dec [arcsec]. | [optional] |
| altdata | {str: (bool, date, datetime, dict, float, int, list, str, none_type)}, none_type | Misc. alternative metadata stored in JSON format, e.g. `{'calibration': {'source': 'ps1', 'color_term': 0.012}, 'photometry_method': 'allstar', 'method_reference': 'Masci et al. (2015)'}` | [optional] |
| assignment_id | int, none_type | ID of the classical assignment which generated the photometry | [optional] |
| flux | float, none_type | Flux of the observation in counts. Can be null to accommodate upper limits from ZTF1, where no flux is measured for non-detections. If flux is null, the flux error is used to derive a limiting magnitude. | [optional] |
| dec | float, none_type | ICRS Declination of the centroid of the photometric aperture [deg]. | [optional] |
| alert_id | int, none_type | Corresponding alert ID. If a record is already present with identical alert ID, only the groups list will be updated (other alert data assumed identical). Defaults to None. | [optional] |
| ra_unc | float, none_type | Uncertainty on RA [arcsec]. | [optional] |
