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).

Example:
Noise,/overplot

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
