   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
   5 ; v11 add the new computer config (see the end)
   6 ; v12 updated at MCBT, Nov. 6th, 2012
   7 ; v13 update pako commands, new setup for NIKA, Nov. 14, 2012, SL

   9 --------- XEphem usage -------------------------------------------------
  10 !! preliminary: if you want to use xephem with the position of the telescope displayed in real time
  11 ! run the following sequence from the command prompt 
  12 slogin mrt-lx3
  13 ps xa |grep azElToXephem.py & ! check if the script is already running, if not do the following
  14 useNCS
  15 azElToXephem.py &
  16 ! once the script is running type:
  17 /vis/xephem/xephem
  18 
  19 ------- Managing Imbfits file -----------------------------------------------
  20 ; Telescope fits are in mrt-lx1
  21 /ncsServer/mrt/ncs/data/imbfits/bol
  22 on mrt-lx1 (not gra-lx1)
  23 
  24 or best
  25 /ncsServer/mrt/ncs/data/20120604/scans
  26 
  27 /ncsServer/mrt/ncs/data/20120604/datastreams/bbc
  28 
  29 processed imbfits files are
  30 /ncs/data/imbfits/bol/
  31 ; Or in ?
  32 /ncsServer/mrt/ncs/data/datastreams/nika/2012
  33 ; Or in ?
  34 /ncsServer/mrt/ncs/data/imbfits/bol
  35 
  36 ; There is a script to copy imbfits files from Iram to sami locally e.g.
  37 ./Backup_telescope.bash 20121024
  38 
  39 ; To process NIKA raw data files onto fits files and imbfits files
  40 ; log in sami on a dedicated window

  62 !!! The observer should be able to run @ini to have all the following commands in the script file
  63 !!!  Attention, ini is the new init file for NIKA, do not use the old nini which will create problems !!!
  64 
  65 
  66 !!! Check that the NCS knows the current project is t21
  67 !!! otherwise the telescope will not obey you pako commands !
  68 !!! --> look at the OperatorControl screen and/or ask the operator
  69 
  70 set project t21

  83 ! azimuth overlap you want to set the origin of the 360 degrees azimuth circle
  84 ! May be usefull to avoid a complete turn (>8min) to go from one source ot another
  85 SET TOPOLOGY LOW ! selects to use the azimuth range 60 to 420 degrees 
  86 SET TOPOLOGY HIGH ! selects to use the azimuth range 100 to 460 degrees

 136 ! procedures for tunning:
 137 @ diy-test-00.pako ! 11 seconds track with 440 330 RA DEC offset to tune NIKA resonances
 138 !   Note the text parameter "Tune" is sent through NCS (then Elvin) to be used by data acquisition
 139 ! 
 140 @ diy-test-03.pako ! big 600x600 arcsec OTF map with 66 steps of 20" each, and 10 seconds pause
 141 !  at each end of subscan for frequency tunning, the text parameter sent by NCS is "big OTF with tunes"
 142 !
 143 @ diy-test-12.pako ! sky dip from 1.1 to 3.5 airmass by step of 0.4, with 11 sec for tunning
 144 !  followed by 22 sec for measure at each step, the text parameter sent by NCS is "tuned Tip"
 145

 158 
 159 !! Attention to the tracking speed (= subscan length / totf) if you choose >10"/s keep an eye
 160 !! on the tracking errors trackAz and trackEl in real time on the telescope control screen
 161 !! this information is also stored in the FITs files (you can go much faster, 
 162 !! check tabble of speed limit depending on elevation
 163 
 164 ! Correct pointing to center on the array by giving a and b
