The CCD package includes possibilities, before doing the actual calibration step(s), to correct for bad pixels in the CCD calibration frames. This correction is applied via the command FIXPIX/CCD and based on existing MODIFY commands. Except for the input and output frame the FIXPIX/CCD command accepts two more parameters in the command line: the correction method to be applied and the MIDAS containing the bad pixel(s) of bad pixel areas(s). Default value for these two parameters are stored in the keywords FX_METH and FX_FILE. In addition to these keywords three other keywords exist to control the correction procedure: FX_FACT, FX_FPAR, and FX_NOISE. The use of the these keywords depend on the correction method applied.
Currently, the required format of the table file depends on the correction method to be applied. Below you can find a listing of the method available and with FX_ keywords involved.
