The sourceStatus field was primarily for indicating plate processing information, but augmented to show original catalog if it did not come from a plate observation.
Digit (counting from right) | Flag | 0 | 1 | 2 | 3 |
|---|---|---|---|---|---|
| 1 | Number of plates on which this object appeared. | This may include plate observations that were excluded from the GSC2.3. | These two digits are read together as an ordinary base ten number, eg, 04 or 12. | - | - |
| 2 | |||||
| 3 | Centroider type associated with the exported position |

| 4 | Quality of exported J magnitude | not present | fit | extrapolated | - |

| 8 | Classification voters | More than one 15um scan | One 15um scan | More than one 25um scan | One 25um scan |
| 9 | Incomplete processing | Completed processing on all plates | Object was too big to be cut out (> 256x256 pixels) on at least one plate | - | - |
| 10 | Deblended object | Single object on all plates | Child (deblended) object on at least one plate | - | - |
GSC 2.4.0 and earlier : 99999900 = TYCHO; 88888800 = Skycat; 77777700 = 2MASS
GSC 2.4.1 and later : Sources from Catalogs have source code x 100 as sourceStatus (e.g. sdss = 1700)
