 Before 10 deg twilight, you can do all the steps in 8 (''i.e.'', this one).
 
-1. Start the mayall-idl:1 VNC session.

 B. type: ~/bin/vnc
 C. Now double click the VNC gui in the mayall-2 dock (i.e., the thing with all the icons at the bottom of the bottom left terminal). 
 This launches a dialog box asking if you want to connect to mayall-idl.kpno.noao.edu:1 . Say "connect" and type in the mzls password. 
 The VNC starts up.

-
- The VNC session should automatically start MUPTILES, MOSSTAT and COPILOT.  Rearrange as desired.
-
- If it doesn't, open terminals in the VNC session and manually run the scripts for monitoring the observations and updating the tile file:
-
- 1a) The FITS file listing which tiles have been completed should be updated throughout the night.
- 
- This file is '''$MOS3_OBS/obstatus/mosaic-tiles_obstatus.fits'''.  The following IDL command will monitor exposures as they are taken throughout the night, automatically updating this file.
-
- From a terminal on the mayall-idl VNC, in the mzls account, start this running:
-{{{
-idl
-   muptiles

- At the end of the night, you should check the updated tile file into the svn repository.
-
- 1b). In a second terminal on the VNC tart the automated script for monitoring the data quality

-   mosstat_continuous

- This will run mosstat on each frame as it shows up and display the results on the screen.
