    286286    a. The FITS file listing which tiles have been completed should be updated throughout the night.
    287287       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.
    288 
    289288       From a terminal on the mayall-idl VNC, in the mzls account, start this running:
    290289       {{{
    … …  
    306305 1. Take a zero image to ensure everything is working. Once the image has been written, use the IRAF window and run mscstat <filename> to make sure the system came up OK. See step [6] above.
    307306 1. Set the focus to some approximate value based on the Truss temperature and the formula:
    308        
    309         Focus(zd) = -8400+(1.4-Ttruss)x110
    310  
    311     where Ttruss is in deg C.
     307    {{{   
     308Focus(zd) = -8400+(1.4-Ttruss)x110
     309    }}}
     310    where `Ttruss` is in deg C.
    312311 1. Ask the telescope operator to point to the first tile in the json file in pass 2 (for normal case, or json of forced pass if starting up non standard). Then ask the telescope to go to a  nearby 5th mag star and to center it on the MOSAIC3 focal plane. The coordinates of the first tile can be found by:
