sara_spec.write_overscan(length, width, left, right)

Write the CCD size and overscan information to a file

The overscan is written as 01-CalibrationMasters/overscan.dat

Parameters

• length – the long size of the CCD (the dispersion direction, columns)

• width – the short size of the CCD (the cross-dispersion direction, rows)

• left – the column at which the overscan ends on the left size of the ccd (thus ignoring column 0-left)

• right – the column at which the overscan stars on the right size of the ccd (thus ignoring column right-length)

Todo

Add checks that right<left, and right <= length
