Figure 1: Making a 2000 second exposure of type ``object".

Figure 2: Parameter file detpars.

Figure 3: The command ccdinfo produces a listing of the current parameters in effect on the chip, and shows what ordinal number to use in detpars to set the gain to a particular number of /ADU.

Figure 4: The rather uninteresting parameter file instrpars. If you are using the scan-table at the 4-m, set instrname to pfccd; otherwise, set this to test.

Figure 5: An example of obspars is shown.

Figure 6: The rather uninteresting parameter file telpars contains only one crucial entry, the telescope name.

Figure 7: Parameters for wfits.

Figure 8: A focus sequence of seven 10-sec exposures, centered at a focus of 1260, with a double space between the focus=1300 and focus=1320.

Figure 9: Running obsinit will reset all ICE and IRAF parameters back to their default values.

Figure 10: Sending images home electronically.

Figure 11: Copying images from the mountain to downtown.

Figure 12: A run of specfocus on 7 focus exposures, in which the camera focus began with a value of 1430 and was stepped by 10 units for each exposure.

Figure 13: The observer is seen endlessly repeating the sequence of a 20 sec exposure in filter 5 with title ``WR7 u" (focus set to 1240) followed by a 10 sec exposure in filter 4 with title ``WR7 b" (focus set to 1260). The observer eventually goes insane and turns to writing manuals for pleasure.

Figure 14: A simple script that repeats the observing sequence discussed in the previous figure as many times as you'd like. The observer is free to go have some coffee and think deep thoughts.

Figure 15: How to get the most up-to-date copy of this manual.
