Having obtained some background, let us now start to process the input
frames according to the scheme in Section 3.7.
As indicated in that section the reduction sequence consists, in a
simplified version, of the following steps:
Processing the Data
- determine overscan correction and trim area;
- preparing calibration frames;
- do the corrections;
- apply the bad pixel corrections.
