Notes on individual flags

  1. 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.
  2. Weird source Indicates that the source has an isolated extremely bright pixel.
