# For Gals. with known (hel.) velocity # Spectral Line Setup file: a9999a.sls generated by AO-Control # N.B. this file can also be used as a standalone script # This file can be used to obtain a 21-cm spectrum of a # galaxy with a known (heliocentric) velocity. # Summary: BW= 12.5 MHz & 6.25 MHz, 9-level sampling # 2 sbcs/polarization, 2048 lags/sbc, 6 sec records, L-narrow receiver # 1.3 km/s & 0.65 km/s resolution. #This file is available at http://www.naic.edu/~koneil/files/a9999a.sls #BE SURE TO CHANGE a9999 -> YOUR PROJ NUMBER! #Can change the rfcfr to the rest frequency of your line. #Can change rcvnum & trkinit command to from 6 -> 5 #and lb -> lbw to go from l-narrow to L-wide. #Uncomment the lbfb line and insert the correct filter #number, and uncomment the setcal and the lbwpol lines #if you're using the L-wide receiver. # Goto working directory, open log and catalog files cd /share/obs4/usr/a9999 logOpen a9999.log srcfile src.list # Source the standard procedure which is invoked as 'dosrc' source /share/obs4/usr/a9999/onoff.tcl # Set correlator board and mean RF center frequencies set sbfr1 1420.405751786 set sbfr2 1420.405751786 set sbfr3 1420.405751786 set sbfr4 1420.405751786 set rfcfr 1420.405751786 # Setup Doppler corrections dopsetfrq $rfcfr $sbfr1 $sbfr2 $sbfr3 $sbfr4 dopsetvel 0 hel dopsetsball dopsetdoit # Set cal setcal hcal # Assert VLBI tone cal off acvlbical off # Adjust IF power levels adjpwrif1 adjpwrif2 -e 3 # Correlator setup parameters calport 1 corcal 0 set estart 1 set dumplength 50000000 set lagsam "0 1 0 1" set lags "2048 2048 2048 2048" set icyc 6 set bandwd "3 3 3 3" set corbrds "6 7 8 9" mcp setup corProg@cor " cor_lagc $lagsam cor_dblnyquist f cor_bwnum $bandwd cor_lagspersbc $lags cor_extstart $estart cor_adjpwr FALSE cor_dmplen $dumplength cor_chiptestmode FALSE cor_dmpsperinteg $icyc cor_dataformat 3 3 3 3 cor_rdpowcntr TRUE cor_relbitshift 0 cor_rdtotcnts FALSE cor_enablanking FALSE cor_brdlist $corbrds" disc on cor "cor_adjpwr false cor_rdp t" # END of spectral line setup file: a9999a.sls ********************************************************************************
