| Name | Type | Description |
|---|---|---|
| filter | string | Filter used for the observation (e.g., u, g, r, or instrument-specific). |
| mag | number | Measured apparent magnitude [mag] of the source in the specified filter. |
| mag_error | number | 1-sigma statistical uncertainty on magnitude [mag]. |
| mag_system | string | Photometric magnitude system (zeropoint convention) for mag and limiting_mag. Default is 'AB'. |
| limiting_mag | number | Limiting magnitude (upper limit) for the observation [mag] in the specified filter. |
| limiting_mag_sigma | number | Significance level [sigma] associated with limiting_mag. Default is 5 (5-sigma upper limit). |
