WFC Dome Flat Assistant

We give some guides about exposure times to be used with WFC and different filters to acquire dome flats with optimum signal (around ~30,000 +/- 1000 counts). We include two dome lightening levels, namely Full and 2/3 setting (corresponding to the marker on the dial pointing to the top left corner of its square casing). The telescope should point to hour angle 0 0 0, declination +80 0 0 (use command 'park flat' in TCS), and the dome should have position 242. The mirror petals should be open, dome shutter closed, and in the dome only the flat lamps on. The CCD with no binning (bin 1x1).
