Noise
Load data from the TM saver and immediately calculate
the system noise temperature using all backends that
were in operation. This routine is tailored for use
at Chalmers Radiometer lab. It makes use of routines
qTsys, which in turn calls
Tsys and TsysAC.
Noise also provides the possibility
to plot the noise temperature calculated on the three different
backends onto a single plot for comparison.
Syntax:
Noise,FILENO
The FILENO argument is an integer value
giving the number of the file to be loaded. This argument
is optional (see qLoad).
Options:
Thot=T,
This is the hot load temperature in Kelvin.
The default value is 291K.
Tcold=T
This is the cold load temperature in Kelvin.
The default value is 111K.
Tmm=[lower,upper],
override plot window range for Tsys. Note the square
brackets.
fmm=[lower,upper],
initial frequency scale. default is maximum range. lower
and upper are integer or float values.
/overplot,
In addition to the individual plots from each backend, plot
all of them together on a single plot.
/noload,
don't load a new file from saver, use the one in memory
