- Bad Pixels A point-source will have this flag set if any pixel within the
photometry aperture, or any within the background annulus, has a corresponding pixel in the quality image with a non-zero value.
Similarly, an extended source will have this flag set if any corrsponding pixel in the quality image has a non-zero value.
The quality image was added to the image file by omcosflag, and a “bad” pixel may either be a damaged
or dead one.
- Weird source Indicates that the source has an isolated extremely bright pixel.
- QFLAG The quality flag for each source in each filter obtained from the
- QFLAG_COMB The quality flag for each source in each filter obtained using the
