   1 PAKO preparation for 2012 run5
   2 -------------------------
   3 ; v9 is at the start of 2012 (copy of v8)
   4 ; v10 is rearranged v9 for the preparation of November 2012, run5

   6 --------- XEphem usage -------------------------------------------------
   7 !! preliminary: if you want to use xephem with the position of the telescope displayed in real time
   8 ! run the following sequence from the command prompt 
   9 slogin mrt-lx3
  10 ps xa |grep azElToXephem.py & ! check if the script is already running, if not do the following
  11 useNCS
  12 azElToXephem.py &
  13 ! once the script is running type:
  14 /vis/xephem/xephem
  15 
  16 ------- Managing Imbfits file -----------------------------------------------
  17 ; Telescope fits are in mrt-lx1
  18 /ncsServer/mrt/ncs/data/imbfits/
  19 het or bol
  20 ; There is a script to copy imbfits files locally e.g.
  21 ; Backup_telescope.bash
  22 ; Edit that file
  23 
  24 ; To process NIKA raw data files onto fits files and imbfits files
  25 ; log in sami on a dedicated window
  26 idl

  29 ---------- Pako usage ----------------------------------------------

  39 ; To start pako
  40 ssh t21@mrt-
  41 gopako
  42 pakodisplay
  43 pako
  44 
  45 !!! Check that the NCS knows the current project is t21
  46 !!! otherwise the telescope will not obey you pako commands !
  47 !!! --> look at the OperatorControl screen and/or ask the operator
  48 
  49 set project t21
  50 set pi "Alain"
  51 set observer "Nika observer"  ! your name here, Nika needs you
  52 
  53 ! If not sending commands (outside normal run) do:
  54 SET DOSUBMIT NO
  55 
  56 SET LEVEL 0 0   ! very verbose
  57 SET LEVEL 1 1   ! chatty
  58 SET LEVEL 3 3   ! less
  59 SET LEVEL 5 5   ! none
  60 
  61 ! Choose one of the 2 azimuth topology possibilities to decide on which end of the 
  62 ! azimuth overlap you want to set the origin of the 360 degrees azimuth circle
  63 ! May be usefull to avoid a complete turn (>8min) to go from one source ot another
  64 SET TOPOLOGY LOW ! selects to use the azimuth range 60 to 420 degrees 
  65 SET TOPOLOGY HIGH ! selects to use the azimuth range 100 to 460 degrees 
  66 
  67 SET ANGLEUNIT arcsec   ! make sure angle units are arcsec.

  77 ! ASK Samuel
  78 RECEIVER /CLEAR 
  79 ! 
  80 ! RECEIVER BOLO ! set pointing mobel of MAMBO2
  81 !! Normaly the default backend for bolo is ABBA (MAMBO2 backend) but thide doesn't exist anymore
  82 !! As a consequence NCS does not record FITS files !!! 
  83 !
  84 ! Attention if there's an incompatibility between RECEIVER and BACKEND IMBFITS are not created either !!!
  85 ! So do can't choose a heterodyne backend with bolo. 
  86 ! To do for Oct 2011 (will be different in the future when NIKA will be integrated to Pako):
  87 RECEIVER E090 /Default   
  88 BACKEND /Clear

  91 ! prepare a catalog
