Next: Running REDUCE/CCD Up: Processing the Data Previous: Processing the Data . Before any processing on the input frame is done, the REDUCE/CCD command will first collect all resources needed for the calibration of the science frame(s). These include the master calibration frames, the overscan offset, and scaling parameters. So, at this point no operations are done yet. ... As an example, suppose the science frame is supposed to corrected for dark current and to be flat fielded. ...
