Meta Index / Home Page / SourceListFile / QUALITY FLAGS

Notes on individual flags

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