Intro

     The 12meter datataking is controlled by a tcl program that runs on galfas2. It is started by a bash script (startp12m). After that the user can enter commands to:

• talk to the pointing program
• control the if/lo
• control the mock spectrometers
• etc.

    Most commands have been embedded in tcl procedures that are called by the user with parameters.

Disc locations for the Tcl functions.

The tcl functions are located in a directory structure

• aosBaseP12m/tcl   -root of tcl functions
• ./startp12m    bash script called by user to start tclsh and initialize things.
• we've made a copy of this in /pkg/aosoft/common/bin/  since this path is added to users path by the system.
  
• gen/   generic tcl routines, 70 functions
• eg: attn, ifsetup,if2, srcget, udc,waitsecs...
• pnt/   pointing related tcl functions, 23 functions
  
• pnt, waittrk, trkinit,lst,  etc
• pnet/  mock spectrometer routines. 39 functions
  
• eg: cross,mapradec,mapsun,mock,psrdolist,recombdolist,mockconfig,mockpset,...
• setups/  setup for observations. 7 functions
• eg. gensetup,psrsetup,recombsetup,setupcross,setupiflo,...
• scripts/startup/  routines used when starting tcl
• tclsh will execute the file .tclshrc  in the home directory when starting up.
• the bash file startp12m plays a few games:
• home directory temporarily set to  scripts/startup
• a .tclshrc file is in that directory
• it sources startup.tcl
• it then resets the home directory to where it was previously
  
• startup.tcl - called bin .tclshrc on startup
• sources init.tcl - doing most of the tcl variable setup
• checks if we are online or running the simulator
• opens connections to mocks, if/lo (if online)
• init.tcl : does most of the variable initialization . called by startup.tcl
• checks if we are online or offline
• adds procedures from various directories. gen,pnt,mock
• if we are off line these may include the simulator routines.

running online, offline

    The datataking is started by the bash script startp12m. It can be run:

• online on galfas2  as user p12m
• this can control the telescope,iflo, and other hardware devices
• offline on ao networked computer.
• the routines that control various hardware devices have been replaced by routines that make dummy calls
• all other routines should work as normal
  
• This lets users check their scripts for tcl errors prior to going online.
• Things like takedata will come back after a 1 second wait.
• Any errors with parameters sent to devices may not be caught.
