| | 1 | === IPP DVO Database Flags === |
| | 2 | |
| | 3 | In the DVO Database, there are bitmask flags associated with images, objects, and detection measurements. For the measurements, there are two types of flags: those generated by the pixel-level photometry analysis (photflags) and those associated with analyses made within the database itself (dbflags). |
| | 4 | |
| | 5 | For photflags, a summary can be found at the following location, along with an explanation of using bitmask flags. |

| | 8 | |
| | 9 | For dbflags, the values are listed below and defined in: |
| | 10 | |
| | 11 | http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/browser/trunk/Ohana/src/libdvo/include/dvo.h |
| | 12 | |
| | 13 | The dbflags are not currently (2010.10.15) as firmly defined or set as the photflags: Many of the values are not currently used and may be changed or replaced. |
