  19 pakodisplay
  20 pako
  21 
  22 !!! Check that the NCS knows the current project is t21
  23 !!! otherwise the telescope will not obey you pako commands !
  24 !!! --> look at the OperatorControl screen and/or ask the operator
  25 
  26 set project t21
  27 set pi "Alain"
  28 set observer "Xavier"
  29 
  30 ! If not sending commands (outside normal run) do:
  31 SET DOSUBMIT NO
  32 
  33 SET LEVEL 0 0   ! very verbose
  34 SET LEVEL 1 1   ! chatty
  35 SET LEVEL 3 3   ! less
  36 SET LEVEL 5 5   ! none
  37 
  38 
  39 ! Choose one of the 2 azimuth topology possibilities to decide on which end of the 
  40 ! azimuth overlap you want to set the origin of the 360 degrees azimuth circle
  41 ! May be usefull to avoid a complete turn (>8min) to go from one source ot another
  42 SET TOPOLOGY LOW ! selects to use the azimuth range 60 to 420 degrees 
  43 SET TOPOLOGY HIGH ! selects to use the azimuth range 100 to 460 degrees 
  44 
  45 
  46 SET ANGLEUNIT arcsec   ! make sure angle units are arcsec.
  47 
  48 ! Remember to reset offsets!

  52 ! total power (no secondary wobbler)
  53 SWTOTAL
  54 
  55 ! Choose a well known heterodyne instrument or bolometer for pointing purpose
  56 ! ASK Samuel
  57 RECEIVER /CLEAR 
  58 RECEIVER BOLO ! set pointing mobel of MAMBO2
  59 !
  60 ! Attention if there's an incompatibility between RECEIVER and BACKEND IMBFITS are not created !!!
  61 ! Normaly the default backend for bolo is ABBA (MAMBO2 backend) but thide doesn't exist anymore
  62 ! So do:
  63 BACKEND /Clear
  64 ! Then ee don't know yet which of the following is good, so try and check the IMBFITS
  65 BACKEND /Disconnect
  66 BACKEND BBC /Default
  67 !
  68 ! If there's no IMBFITs then use RECEIVER E090 to use a well known EMIR receiver model
  69 ! it is probably not necessary to define the other receiver options
  70 ! but if needed just use the default RECEIVER /DEFAULT
  71 ! then BBC backend
  72 
  73 
  74 ! prepare a catalog
  75 ! NIKA.sou (see wiki web) to put in the directory : 
  76 !   t21/pako
  77 
  78 ! Choose a catalog with a .sou extension
  79 CATALOG SOURCE NIKA.sou
  80 HELP source
  81 
  82 ! select a source
  83 ! No case matching, but name must be full
  84 SOURCE W3OH
  85 
  86 ! or a planet
  87 SOURCE Mars
  88 
  89 ! to check the catalog

  93 ! Once you have entered an observing mode (See below)
  94 ! if you want that the telescope executes your commands do no forget
  95 SET DOSUBMIT YES
  96 
  97 ! start an observation (MAKE SURE you want that)
  98 START 
  99 ! (if you still have DOSUBMIT NO, nothing happens, but the commands 
 100 ! are in the queue and they will be executed when SET DOSUBMIT YES)

 111 ! On the fly mode (cover all array pixels) for pointing and alignment. Expensive.
 112 OTFMAP -180 -180 180 -180  - ! offsets at start and end of first otf subscan
 113   /notf 61 ! number of subscans
 114   /step 0 6  ! steps between subscans in arcsecond
 115   /system truehorizon ! projection AzEl is used to define the map
 116   /totf 36 ! time of a subscan
 117   /zigzag  ! go back and forth
 118   /reference no ! not necessary except if there's a conflict with /system
 119 
 120 !! Attention to the tracking speed (= subscan length / totf) if you choos >10"/s keep an eye
 121 !! on the tracking errors trackAz and trackEl in real time on the telescope control screen
 122 !! this information is also stored in the FITs files
 123 
 124 ! Correct pointing to center on the array by giving a and b
 125 OFFSET a b /SYSTEM Nasmyth
 126 
 127 ! correct the focus
 128 SET FOCUS -1
 129

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

 185 ! then it is in x and y as above
 186
