Drift Map

This is the optimum mapping routine (in terms of giving the flattest baselines) for the Arecibo/Gregorian system. The intent of the routine is for the user to map an area slightly larger than the area in which he/she is interested. Baseline subtraction then occurs via fitting a baseline between the opposite ends of each scan (Figure 1).


Example showing 'typical' mapping techniques for baseline removal.

A number of decisions have to be made when running this routine:
