Sample reductions

The following two sections show sample reductions of real photometric data, first by the long winded method of typing each of the SURF commands in turn and then using the perl [6] script scuquick which provides some level of automation.

For the first example, I'll use two 20 integration observations of the radio galaxy 3C 31 which were made at 2.0 mm during the astronomical commissioning on a poor night (the zenith optical depth at 225 GHz was about 0.1). I'll use change_flat to change the flatfield file although, since we are using one of the photometric pixels, flatfielding is not necessary.
