Other DEBIAS functions
DEBIAS is the most complex of the initial reduction programs and
performs much more than just debiassing. Its other functions are:
- Error estimation/propagation.
- Defect removal (possibly using an ASCII regions definition
file).
- Gain correction (converting data values into electrons).
- Deferred charge correction (if you must).
- Saturated pixel detection.
- Extraction of the useful CCD area.
For details about these functions see
the full description.
