General purpose scripts @ GMRT These scripts work on any astro*/gtac* machines. Please prefere to execute these scripts in /scratch or /temp areas to avoid disk space problems. For help please contact to snk@gmrt.ncra.tifr.res.in . ## RANTSOL: plots antenna amplitude and phase wrt channel nos from lta file(gsb) using rantsol without normalisation. ~astrosupp/perl/gain_chan0.pl ## RANTSOL: plots antenna amplitude and phase wrt channel nos from lta file(gsb) using rantsol with normalisation(amp only) using first(scan) gain value. ~astrosupp/perl/gain_chan1.pl ## RANTSOL: plots antenna amplitude and phase wrt channel nos from lta file(gsb) using rantsol with normalisation(amp only) using averaged(scans) gain value. ~astrosupp/perl/gain_chan2.pl ## RANTSOL: plots antenna amplitude and phase wrt time from lta file(gsb) using rantsol. this works for single channel no. ~astrosupp/perl/gain_time.pl ## XTRACT: plots antenna self power wrt channel nos from lta file(gsb/gwb) using xtract. ~astrosupp/perl/self_chan_v0.pl (for each time stamp individual plots) ~astrosupp/perl/self_chan_v1.pl (for each time stamp overlap plots) ## XTRACT: plots antenna cross amplitude and phase wrt time from lta file(gsb) using xtract. this works for single channel no. ~astrosupp/perl/cross_time.pl ## LTA_FREQ_CHAN: converts frequency to channel-no and vice versa ~astrosupp/perl/ltafreqchan.pl ## SERVO DATA: servo data files : /media/usb/data/ (only on oper2) e.g. "/media/usb/data/09Dec2015_000000.srv" plotting script area : /media/usb/plot_servo_data/ plotting script name : plot_servo_data.pl list of servo parameters # 1 day # 8 azim_tp # 14 elev_tp # 20 wind1 # 25 dig3 # 2 month # 9 azim_cp # 15 elev_cp # 21 wind2 # 26 dig4 # 3 date # 10 az_motor1 # 16 el_motor1 # 22 dig0 # 27 dig5 # 4 time # 11 az_motor2 # 17 el_motor2 # 23 dig1 # 28 az_err # 5 year # 12 vars.az_tacho1 # 18 vars.el_tacho1 # 24 dig2 # 29 el_err # 6 abctime # 13 vars.az_tacho2 # 19 vars.el_tacho2 # 7 servotime ## SOURCE LIST CONVERSION converts jpl/nasa source list format to GMRT source list format help : ~astrosupp/perl/coord/coord.pdf script : ~astrosupp/perl/coord/jpl_nasa_to_gmrt_src_list.pl input : ~astrosupp/perl/coord/horizons_results.txt output : ~astrosupp/perl/coord/mars.list & mars.cmd ## SATELLITE PASSES CHECK (only on astro1) this script checks for any satellite passes overlap while observing. script : ~astrosupp/perl/sate/sate_check.pl input : lta file output : summry (text file) ## Point the GMRT antennas to the given GPS position ~astrosupp/perl/point_dish.pl (only on astro1 and krithika)
