At start of night, check telescope pointing and zero the telescope coordinates using a bright star placed on the telescope boresight (defined as the center of the mosaic3 focal plane).206 2. Move to the beginning of the first MzLS tile position207 3. Focus the telescope204 1. Take a zero image to ensure everything is working 205 2.

Focus the telescope 208 208 - create a focus script using the NGUI 209 209 - run the focus script from the /home/observer/exec directory … … 219 219 === Observe - all night long! === 220 220 221 Execute mzls*sh script 222 223 In a nocs terminal window (on the mosaic3 computer): 224 Go to /home/observer/exec, and execute the mzls*.sh script. 225 226 Monitor focus by checking the image quality on each frame. Keep track of the truss temperature variation and modify 221 5. From the mzls@mayall-idl window, generate the top-level observing script (tonight.sh) assuming 222 that we have three plan files named pass1.json, etc. 223 {{{ 224 cd ~/obsbot 225 python mosbot.py pass1.json pass2.json pass3.json --script /mosaic3/exec/mosbot/tonight.sh 226 }}} 227 228 6. From the observer@mayall-3 xterm window, start taking exposures using the top-level observing script (tonight.sh): 229 {{{ 230 cd ~/exec/mosbot 231 ./tonight.sh 232 }}} 233 234 7. Monitor focus by checking the image quality on each frame. Keep track of the truss temperature variation and modify 227 235 the focus as needed. The Mayall has astigmatism, so one can tell from the shape of the images which way to move the focus. 228 236 To stop and do a focus sequence:
