Standards 1) Take a standard star observation at the beginning of the night, after each primary field, and at the end of the night. Keep the peak counts below about 8K (you could put the telescope somewhat out of focus, eg 20 units, if necessary). The following standards are used: 9185 22 02 05.7 -01 06 02 J2000 NEAR SSA22 9104 01 03 15.8 -04 20 44 J2000 NEAR NOAO FIELD 9106 03 26 53.9 -39 50 38 J2000 NEAR AXAF FIELD 9111 04 49 54.6 -35 11 17 J2000 NEAR AXAF FIELD 9118 06 22 43.7 -00 36 30 J2000 See also Eric Persson's paper in the control room on infrared standards (with finding charts). 2) Point the telescope to the standard star and offset 192" S and 192" E to put the standard star on chip one. Note that 9106 and some other standards might not appear in the skymap GUI. Once per observing run standards should be observed on all four chips. 3) Click on the "Std" button on the camera control GUI to open the standard observation macro. Select chip 1, a 25" dither step, and dice-5 dither pattern (this will cover all four quadrants of the chip). 4) Check the other parameters on the camera control GUI (eg, 7 second exposure, 1 loop, objtype standard), and click Execute. 5) Inspect images, compare to finder chart in Persson's paper (confirms that got the telescope pointing correct), check that peak counts below 8K, etc.
