    226226will print out a summary of all the frames from 10001 to the present in a nice tabular form (widen the window).  This is useful for checking how the seeing and sky brightness have varied since frame 10001, and whether  one should create and upload a new JSON observing script. The /noprint just prevents the decstat output for every frame; if you want to see that, then don't use the /noprint keyword.

     228=== 10. tonight.sh script stops for any reason ===

     230'''Symptoms:''' Things go idle and quiet.  No exposures are being taken or read out, the telescope is not moving, and the software does not indicate any activity.  The shell window where you are running tonight.sh returns to a prompt, and probably has an error message of some kind.   
     231
     232'''Frequency:''' This happened once on the night of 06/07 March when 4MAPS took a very long time to settle.  The tonight show reported a timeout error on the telescope move command, because the TCS does not report back with "move complete" until 4MAPS finishes settling.
     233
     234'''Fix:''' Re-run the mosbot -py command with the appropriate pass?.json files.  Check that the tonight.sh script has been rebuilt anew.  Start the new tonight.sh script.
