8 ! starts a comment line
9 - command is continued
10 @ filename to execute the script filename

12 ; Telescope fits are in mrt-lx1
13 /ncsServer/mrt/ncs/data/imbfits/
14 het or bol
15
16 ; To start pako
17 ssh t21@mrt-
18 gopako
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 ! Choose one of the 2 azimuth topology possibilities to decide on which end of the
39 ! azimuth overlap you want to set the origin of the 360 degrees azimuth circle
40 ! May be usefull to avoid a complete turn (>8min) to go from one source ot another
41 SET TOPOLOGY LOW ! selects to use the azimuth range 60 to 420 degrees
42 SET TOPOLOGY HIGH ! selects to use the azimuth range 100 to 460 degrees
43
44 SET ANGLEUNIT arcsec ! make sure angle units are arcsec.
45
46 ! Remember to reset offsets!
47 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!
48 OFFSETS /Clear
49
50 ! total power (no secondary wobbler)
51 SWTOTAL
52
53 ! Choose a well known heterodyne instrument or bolometer for pointing purpose
54 ! ASK Samuel
55 RECEIVER /CLEAR
56 !
57 ! RECEIVER BOLO ! set pointing mobel of MAMBO2
58 !! Normaly the default backend for bolo is ABBA (MAMBO2 backend) but thide doesn't exist anymore
59 !! As a consequence NCS does not record FITS files !!! (seen 17/10/2011)
60 !
61 ! Attention if there's an incompatibility between RECEIVER and BACKEND IMBFITS are not created either !!!
62 ! So do can't choose a heterodyne backend with bolo. So for now use only heterodyne devices:
63 RECEIVER E090 /Default
64 BACKEND /Clear
65 BACKEND BBC /Default
66 !
67 ! prepare a catalog
68 ! NIKA.sou (see wiki web) to put in the directory :
69 ! t21/pako
70
71 ! Choose a catalog with a .sou extension
72 CATALOG SOURCE NIKA.sou
73 HELP source
74
75 ! select a source
76 ! No case matching, but name must be full
77 SOURCE W3OH
78
79 ! or a planet
80 SOURCE Mars
81
82 ! to check the catalog
83 HELP SOURCE
84
85 ! Once you have entered an observing mode (See below)
86 ! if you want that the telescope executes your commands do no forget
87 SET DOSUBMIT YES
88
89 ! start an observation (MAKE SURE you want that)
90 START
91 ! (if you still have DOSUBMIT NO, nothing happens, but the commands
92 ! are in the queue and they will be executed when SET DOSUBMIT YES)
93
94 !!!!!!!!! Observing modes !!!!!!!
95
96 ! procedure to focus
97 ! to set focus
98 SET FOCUS 0
99
100 ! On the fly mode (cover all array pixels) for pointing and alignment. Expensive.
101 OTFMAP -180 -180 180 -180 - ! offsets at start and end of first otf subscan
102 /notf 61 ! number of subscans
103 /step 0 6 ! steps between subscans in arcsecond
104 /system truehorizon ! projection AzEl is used to define the map
105 /totf 36 ! time of a subscan
106 /zigzag ! go back and forth
107 /reference no ! not necessary except if there's a conflict with /system
108
109 !! Attention to the tracking speed (= subscan length / totf) if you choos >10"/s keep an eye
110 !! on the tracking errors trackAz and trackEl in real time on the telescope control screen
111 !! this information is also stored in the FITs files
112
113 ! Correct pointing to center on the array by giving a and b
114 OFFSET a b /SYSTEM Nasmyth
115
116 ! correct the focus
117 SET FOCUS -1
118
119 ! Small map to check the focus quickly
120 OTFMAP -48 -48 48 -48 - ! offsets at start and end of first otf subscan
121 /notf 17 ! number of subscans
122 /step 0 6 ! steps between subscans in arcsecond
123 /system truehorizon ! projection AzEl is used to define the map
124 /totf 10 ! time of a subscan
125 /zigzag ! go back and forth
126
127 ! 4 switching modes (3 useful for bolometers)
128 ! total power
129 SWTOTAL
130 ! Beam switching
131 SWBEAM
132 ! wobbler switching negAmplitude posAmplitude 0.6 seconds per phase!
133 SWWOBBLER -30 +30 /TPHASE 0.6

139 POINTING 120
140
141 ! skydip
142 ! stop wobbler
143 SWTOTAL /tphase 0.6
144 ! tip at azimuth 180, scan airmass from 1.1 to 4.1 by steps of 0.6
145 TIP 180 /airmass 1.1 4.1 0.6 /tsubscan 12.0
146
147 ! position switching
148 ONOFF !
149 ! example (give ON offsets and OFF offsets, 2 positions each, 2 systems)
150 ONOFF 30 40 /reference -600 -700 projection /SYSTEM projection
151 ! other options (30 seconds per subscan):
152 /nsubscans 12 /symmetric /tsubscan 30
153
154 ! projection is RADEC system here
155 ! can use /SYSTEM trueHorizon too
156
157 ! if wobbler on use the following special mode
158 ! in that case the off position is automatically on the off wobbler position
159 ONOFF /swwobbler /nsubscans 12 /symmetric /tsubscan 30
160
161 ! not used by bolometers
162 TRACK
163
164 ! everything in J2000
165 ! x=(l-lsource)*cos(b)
166 ! y=b-bsource
167 ! to define the source
168 SOURCE
169 ! if needs to offset from source use
170 OFFSET a b /SYSTEM projection
171 ! then it is in x and y as above
172
173 ! or
174
175 OFFSET a b /SYSTEM trueHorizon
176 ! then Delta az= (az-azsource)*cos(elev)
177 ! and Delta el= elev-elevsource
178
179 ! or
180 OFFSET a b /SYSTEM Nasmyth
181
182 ! Remember to reset offsets!
