gbt_tsys

function gbt_tsys(scan, [ifnum=integer], [intnum=integer], [fdnum=integer], [caltype=string], [ifile=string], [pol=string], [print=string])

This program gets the system temperature, with frequency for a single scan which has both cal phases in it. The program looks at only one if, polarization, feed, etc. at time. It also assume that if the polarization hybrid is placed in the IF path the correct polarization ends up in the fits file (e.g. RR instead of XX). This idea has not yet been tested, to my knowledge, but it should be true. Note that is you do not give a caltype, the program assumes you used the high cal, which is preferred for this type of observation. If you did not fire the high cal (that is, the noise diode with high voltage), you must say so, as this information is NOT recorded in the sdfits files.

Parameters
scan
in, required
integer 		M&C scan number

Keywords
ifnum
in, optional
integer 		IF number (starting with 0)
intnum
in, optional
integer 		Integration number (default=all}
fdnum
in, optional
integer 		feed number (default 0)
caltype
in, optional
string 		'hi' or 'lo' voltage fired for the cal (default is 'hi')
ifile
in, optional
string 		the sdfits file from which the scan is taken. This is needed if there are more than one observations with the same scan number (e.g. if the dirin command was used)
pol
in, optional
string 		the polarization to use. Options are 'XX', 'YY', 'XY', 'YX', 'RR', 'LL', 'RL', 'LR' (default is 'XX')
print
in, optional
string 		print the system temperature result? (default is 'T')
