  -o     # object                "3C48|1833"# default all sources
  -c     # channel no.           "150"      # default 150
  -i     # int time              "16"       # default 1 
  -r     # ref antenna           "C09"      # default first antenna in array 
  -p     # pol                   "130/175"  # default both 
  -a     # plotting antenna list "C00 C01 C02..."           # default all antennas 

   ## do not use "-s" and "-o" simultaneously 
   ## always use " " for multipal objects ( e.g. "3C48|1833" )
   ## example

/home/gpuuser/bin/gainplot.pl -f /rawdata/02feb/test.lta -c "150" -o "3C|18" -p 130 -r C00 
/home/gpuuser/bin/gainplot.pl -f /rawdata/02feb/test.lta -s 0 -c  "150"  -p 130 -r C00 

NOTE : this creates pdf file..... just open it using evience....and look at the plots....

 
eg :

[gpuuser@gwbh1 ~]$ gainplot.pl -f /data2/gpuuser/09sep/test_09sep205_lta4ch2ktotint_tpaonline_bw200_1450lo.lta -r C04
wrt time ampl & phase..... default channel taken 150.

[gpuuser@gwbh1 ~]$ gainplot.pl -f /data2/gpuuser/09sep/test_09sep205_lta8ch16k2stokes_bw400_1450lo.lta -c 2100 -r C00
channel Number depends upon : total ch., freq and bandwidth used...  for 2k mostly take 800 to 1000 for all bands....
for 4k..... 
for 8k.....
for 16k.... channel 2000 to 2400
