Processing the Data
</H1>
 Having obtained some background, let us now start to process the input 
 frames according to the scheme in Section&nbsp;<A HREF="node41.html#ccd:basic-reduction-steps">3.7</A>. 
 As indicated in that section the reduction sequence consists, in a
 simplified version, of the following steps:
 <DL COMPACT>
<DT>1.
<DD>determine overscan correction and trim area;
<DT>2.
<DD>preparing calibration frames;
  <DT>3.
<DD>do the corrections;
  <DT>4.
<DD>apply the bad pixel corrections.
 </DL>
