Parameters
scans
in, required
integer array 		The scan numbers to calibrated (using getps) to determine system temperatures and ultimately opacity.
opacity
in/out, required
variable 		The initial guess on input and the fitted value on output for the opacity.

Keywords
ifnum
in, optional
integer 		The standard GBTIDL ifnum argument. This defaults to 0 if not supplied.
plnum
in, optional
integer 		The standard GBTIDL plnum argument. This defaults to 0 if not supplied.
fdnum
in, optional
integer 		The standard GBTIDL fdnum argument. This defaults to 0 if not supplied.
tatmos
in, optional
float 		The atmospheric temperature, in K, to use in the fit. This defaults to 270.0 if not supplied.
