Start the mayall-idl:1 VNC session.277 {{{278 A.In a terminal window from mayall-2, ssh to mzls@mayall-idl and log in using the mzls password276 1.

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). 281 281 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. 282 282 The VNC starts up. 283 }}} 284 285 The VNC session should automatically start MUPTILES, MOSSTAT and COPILOT. Rearrange as desired. 286 287 If it doesn't, open terminals in the VNC session and manually run the scripts for monitoring the observations and updating the tile file: 288 289 1a) The FITS file listing which tiles have been completed should be updated throughout the night. 290 291 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. 292 293 From a terminal on the mayall-idl VNC, in the mzls account, start this running: 294 {{{ 295 idl 296 muptiles 297 }}} 298 At the end of the night, you should check the updated tile file into the svn repository. 299 300 1b).
