Bad Pixels A point-source will have this flag set if any pixel within the
photometry aperture have 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.
