PAKO preparation for 2012 run5 ------------------------- ; v9 is at the start of 2012 (copy of v8) ; v10 is rearranged v9 for the preparation of November 2012, run5 ; v11 add the new computer config (see the end) ; v12 updated at MCBT, Nov. 6th, 2012 --------- XEphem usage ------------------------------------------------- !! preliminary: if you want to use xephem with the position of the telescope displayed in real time ! run the following sequence from the command prompt slogin mrt-lx3 ps xa |grep azElToXephem.py & ! check if the script is already running, if not do the following useNCS azElToXephem.py & ! once the script is running type: /vis/xephem/xephem ------- Managing Imbfits file ----------------------------------------------- ; Telescope fits are in mrt-lx1 /ncsServer/mrt/ncs/data/imbfits/bol on mrt-lx1 (not gra-lx1) or best /ncsServer/mrt/ncs/data/20120604/scans /ncsServer/mrt/ncs/data/20120604/datastreams/bbc processed imbfits files are /ncs/data/imbfits/bol/ ; Or in ? /ncsServer/mrt/ncs/data/datastreams/nika/2012 ; Or in ? /ncsServer/mrt/ncs/data/imbfits/bol ; There is a script to copy imbfits files from Iram to sami locally e.g. ./Backup_telescope.bash 20121024 ; To process NIKA raw data files onto fits files and imbfits files ; log in sami on a dedicated window idl convert_fits_files2 ---------- Pako usage ---------------------------------------------- !!!! Interface to NCS Summary of PAKO user's manual ! starts a comment line - command is continued @ filename to execute the script filename ; To start pako ; Devant l'ordinateur de commande : login as t21 ssh t21@mrt-lx1.... gopako pakodisplay pako !!! The observer should be able to run @nini to have all the following commands in the script file !!! Check that the NCS knows the current project is t21 !!! otherwise the telescope will not obey you pako commands ! !!! --> look at the OperatorControl screen and/or ask the operator set project t21 set pi "Alain" set observer "Nika observer" ! your name here, Nika needs you ! If not sending commands (outside normal run) do: SET DOSUBMIT NO SET LEVEL 0 0 ! very verbose SET LEVEL 1 1 ! chatty SET LEVEL 3 3 ! less SET LEVEL 5 5 ! none ! Choose one of the 2 azimuth topology possibilities to decide on which end of the ! azimuth overlap you want to set the origin of the 360 degrees azimuth circle ! May be usefull to avoid a complete turn (>8min) to go from one source ot another SET TOPOLOGY LOW ! selects to use the azimuth range 60 to 420 degrees SET TOPOLOGY HIGH ! selects to use the azimuth range 100 to 460 degrees SET ANGLEUNIT arcsec ! make sure angle units are arcsec. ! Remember to reset offsets! !!!!!!!!!!!!!!!!!!!!!!!!!!!!! OFFSETS /Clear ! total power (no secondary wobbler) SWTOTAL ! Choose a well known heterodyne instrument or bolometer for pointing purpose ! ASK Samuel RECEIVER /CLEAR ! ! RECEIVER BOLO ! set pointing mobel of MAMBO2 !! Normaly the default backend for bolo is ABBA (MAMBO2 backend) but thide doesn't exist anymore !! As a consequence NCS does not record FITS files !!! ! ! Attention if there's an incompatibility between RECEIVER and BACKEND IMBFITS are not created either !!! ! So do can't choose a heterodyne backend with bolo. ! To do for Oct 2011 (will be different in the future when NIKA will be integrated to Pako): RECEIVER E090 /Default BACKEND /Clear BACKEND BBC /Default ! ! prepare a catalog ! NIKA.sou (see wiki web) to put in the directory : ! t21/pako ! Choose a catalog with a .sou extension CATALOG SOURCE NIKA HELP source ! select a source ! No case matching, but name must be full SOURCE W3OH ! or a planet SOURCE Mars ! to check the catalog HELP SOURCE ! Catalog of Pointing source from IRAM CATALOG SOURCE iram-J2000 ! Once you have entered an observing mode (See below) ! if you want that the telescope executes your commands do no forget SET DOSUBMIT YES ! start an observation (MAKE SURE you want that) START ! (if you still have DOSUBMIT NO, nothing happens, but the commands ! are in the queue and they will be executed when SET DOSUBMIT YES) !!!!!!!!! Observing modes !!!!!!! ! procedure to focus ! to set focus correction in mm wrt the current focus SET FOCUS -2.4 ! On the fly mode (cover all array pixels) for pointing and alignment. Expensive. OTFMAP -180 -180 180 -180 - ! offsets at start and end of first otf subscan /notf 61 ! number of subscans /step 0 6 ! steps between subscans in arcsecond (az el) /system truehorizon ! projection AzEl is used to define the map /totf 36 ! time of a subscan /zigzag ! go back and forth /reference no ! not necessary except if there's a conflict with /system !! Attention to the tracking speed (= subscan length / totf) if you choos >10"/s keep an eye !! on the tracking errors trackAz and trackEl in real time on the telescope control screen !! this information is also stored in the FITs files ! Correct pointing to center on the array by giving a and b ! Pointing corrections should be done in az, el, not nasmyth, R. Zylka private communication OFFSET 0 0 /SYSTEM Nasmyth ! Small map to check the focus quickly OTFMAP -48 -48 48 -48 - ! offsets at start and end of first otf subscan /notf 17 ! number of subscans /step 0 6 ! steps between subscans in arcsecond /system truehorizon ! projection AzEl is used to define the map /totf 10 ! time of a subscan /zigzag ! go back and forth ! 4 switching modes (3 useful for bolometers) ! total power SWTOTAL !
