| 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: |
| Index Type | Key or Field List |
| primary key | objID |
| foreign key | PhotoObjAll(objID) |
| covering index | mode, l, b, raErr, decErr, raDecCorr |
| covering index | l, b, objID, mode |
| covering index | b, l, objID, mode |
