| The extra columns that didn't make it into the PhotoObjAll table. |
| These are added as a separate table because adding columns to the very large PhotoObjAll table is prohibitively expensive unless the table is reloaded from scratch. In a future release, these columns will be added to the PhotoObjAll table. In the meantime, to access these columns, you may join with the PhotoObjAll table on the objid: |
| name | type | length | unit | ucd | description |
| objID | bigint | 8 | ID_MAIN | Unique SDSS identifier composed from [skyVersion,rerun,run,camcol,field,obj]. | |
| mode | tinyint | 1 | CLASS_OBJECT | 1: primary, 2: secondary, 3: family object. | |
| l | float | 8 | deg | POS_GAL_LAT | Galactic latitude |
| b | float | 8 | deg | POS_GAL_LON | Galactic longitude |
| raErr | float | 8 | arcsec | POS_EQ_RA_ERR | Error in RA |
| decErr | float | 8 | arcsec | POS_EQ_DEC_ERR | Error in dec |
| raDecCorr | float | 8 | CODE_MISC | RA/dec correlation |
