Meta Temperature Controller and Web-Status Update

The Meta Temperature Controller status web-page is updated by a combination of scripts started by a cron job on the observer workstations at Clay and scripts running on the webserver at SBS.

crontab at LCO:

  */5  * * * * ./PFS/pfs_log.csh &> /dev/null 
  */20 * * * * sleep 10 ; ./PFS/pfs_scp.csh &> /dev/null

  3    9 * * * ./PFS/ionp.csh $HOME/.pfs.log birk@xxx,crane@xxx,ian@xxx

pfs_log.csh:

  #! /bin/csh -f

  setenv PFSBIN  $PFSHOME/src
