   1 PAKO preparation for 2011
   2 -------------------------
   3 
   4 !! preliminary: if you want to use xepehm with the position of the telescope displayed in real time
   5 ! run the following sequence from the command prompt 
   6 slogin mrt-lx3
   7 ps xa |grep azElToXephem.py & ! check if the script is already running, if not do the following
   8 useNCS
   9 azElToXephem.py &
  10 ! once the script is running type:
  11 /vis/xephem/xephem
  12 
  13 
  14 !!!! 
  15 Interface to NCS
  16 Summary of PAKO user's manual
  17 
  18 
  19 !   starts a comment line
  20 -   command is continued
  21 @ filename   to execute the script filename
  22 
  23 ; Telescope fits are in mrt-lx1
  24 /ncsServer/mrt/ncs/data/imbfits/
  25 het or bol
  26 
  27 ; To start pako
  28 ssh t21@mrt-
  29 gopako
  30 pakodisplay
  31 pako
  32 
  33 !!! Check that the NCS knows the current project is t21
  34 !!! otherwise the telescope will not obey you pako commands !
  35 !!! --> look at the OperatorControl screen and/or ask the operator
  36 
  37 set project t21
  38 set pi "Alain"
  39 set observer "Xavier"
  40 
  41 ! If not sending commands (outside normal run) do:
  42 SET DOSUBMIT NO
  43 
  44 SET LEVEL 0 0   ! very verbose
  45 SET LEVEL 1 1   ! chatty
  46 SET LEVEL 3 3   ! less
  47 SET LEVEL 5 5   ! none
  48 
  49 ! Choose one of the 2 azimuth topology possibilities to decide on which end of the 
  50 ! azimuth overlap you want to set the origin of the 360 degrees azimuth circle
  51 ! May be usefull to avoid a complete turn (>8min) to go from one source ot another
  52 SET TOPOLOGY LOW ! selects to use the azimuth range 60 to 420 degrees 
  53 SET TOPOLOGY HIGH ! selects to use the azimuth range 100 to 460 degrees 
  54 
  55 SET ANGLEUNIT arcsec   ! make sure angle units are arcsec.
  56 
  57 ! Remember to reset offsets!
  58 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!
  59 OFFSETS /Clear
  60 
  61 ! total power (no secondary wobbler)
  62 SWTOTAL
  63 
  64 ! Choose a well known heterodyne instrument or bolometer for pointing purpose
  65 ! ASK Samuel
  66 RECEIVER /CLEAR 
  67 ! 
  68 ! RECEIVER BOLO ! set pointing mobel of MAMBO2
  69 !! Normaly the default backend for bolo is ABBA (MAMBO2 backend) but thide doesn't exist anymore
  70 !! As a consequence NCS does not record FITS files !!! 
  71 !
  72 ! Attention if there's an incompatibility between RECEIVER and BACKEND IMBFITS are not created either !!!
  73 ! So do can't choose a heterodyne backend with bolo. 
  74 ! To do for Oct 2011 (will be different in the future when NIKA will be integrated to Pako):
  75 RECEIVER E090 /Default   
  76 BACKEND /Clear
  77 BACKEND BBC /Default
  78 !
  79 ! prepare a catalog
  80 ! NIKA.sou (see wiki web) to put in the directory : 
  81 !   t21/pako
  82 
  83 ! Choose a catalog with a .sou extension
  84 CATALOG SOURCE NIKA.sou
  85 HELP source
  86 
  87 ! select a source
  88 ! No case matching, but name must be full
  89 SOURCE W3OH
  90 
  91 ! or a planet
  92 SOURCE Mars
  93 
  94 ! to check the catalog
  95 HELP SOURCE
  96 
  97 ! Once you have entered an observing mode (See below)
  98 ! if you want that the telescope executes your commands do no forget
  99 SET DOSUBMIT YES
 100 
 101 ! start an observation (MAKE SURE you want that)
 102 START 
 103 ! (if you still have DOSUBMIT NO, nothing happens, but the commands 
 104 ! are in the queue and they will be executed when SET DOSUBMIT YES)
 105 
 106 !!!!!!!!! Observing modes !!!!!!!
 107 
 108 ! procedure to focus
 109 ! to set focus
 110 SET FOCUS 0
 111 
 112 ! On the fly mode (cover all array pixels) for pointing and alignment. Expensive.
 113 OTFMAP -180 -180 180 -180  - ! offsets at start and end of first otf subscan
 114   /notf 61 ! number of subscans
 115   /step 0 6  ! steps between subscans in arcsecond
 116   /system truehorizon ! projection AzEl is used to define the map
 117   /totf 36 ! time of a subscan
 118   /zigzag  ! go back and forth
 119   /reference no ! not necessary except if there's a conflict with /system
 120 
 121 !! Attention to the tracking speed (= subscan length / totf) if you choos >10"/s keep an eye
 122 !! on the tracking errors trackAz and trackEl in real time on the telescope control screen
 123 !! this information is also stored in the FITs files
 124 
 125 ! Correct pointing to center on the array by giving a and b
 126 OFFSET a b /SYSTEM Nasmyth
 127 
 128 ! correct the focus
 129 SET FOCUS -1
 130 
 131 ! Small map to check the focus quickly
 132 OTFMAP -48 -48 48 -48  - ! offsets at start and end of first otf subscan
 133   /notf 17 ! number of subscans
 134   /step 0 6  ! steps between subscans in arcsecond

 163 ! other options (30 seconds per subscan):
 164 /nsubscans 12 /symmetric /tsubscan 30
 165 
 166 ! projection is RADEC system here
 167 ! can use /SYSTEM trueHorizon too
 168 
 169 ! if wobbler on use the following special mode
 170 ! in that case the off position is automatically on the off wobbler position
 171 ONOFF /swwobbler /nsubscans 12 /symmetric /tsubscan 30

 181 ! if needs to offset from source use
 182 OFFSET a b /SYSTEM projection
 183 ! then it is in x and y as above
 184 
 185 ! or
 186 
 187 OFFSET a b /SYSTEM trueHorizon
