 4. Monitor focus by checking the image quality on each frame or keeping an eye on the mosstat PSF display. Keep track of the truss temperature variation and use the information to modify  the focus as needed. Note that the focus may not respond quickly to changes in temperature, so monitor the images carefully before adjusting focus.  The Mayall has astigmatism, so one can sometimes tell from the shape of the images which way to move the focus.  To stop and do a focus sequence:
-- Create a file to tell obsbot to quit
+- Create a file to tell tonight.sh to quit. On mosaic3:
 {{{
    touch ~/exec/mosbot/quit
 }}}
-- Wait for the current exposure to complete (at which point the above file is automatically removed)
-- Run a focus sequence (see link below for instructions)
+- Wait for the current exposure to complete (at which point the above file is automatically removed). 
+- CTRL-C the mosbot.py session on mayall-idl.
+- Run a focus sequence (see link below for instructions).
   - [wiki:MayallZbandLegacy/NotesforObservers/FocusInfo Example of a focus sequence]
 - Re-start the observing as described above.  **IMPORTANT** make sure to re-run `mosbot.py` so that you don’t repeat exposures from the beginning of the night!
