initialize window

Synopsis
initWindow(nbands, fCenter, fWidth, fRes)

Description

function that defines a spectral window, computes absorption and emmision coefficients for this window, using the above atmospheric parameters.

Arguments

nbands	in	number of bands
		Allowed:	Int, standing for the number of bands
		Default:	1
fCenter	in	frequencies
		Allowed:	Quantum with a vector value and unit of frequency, Hz
		Default:	'88.e9Hz'
fWidth	in	frequency width
		Allowed:	Quantum with a vector value and unit of frequency, Hz
		Default:	'5.0e8Hz'
fRes	in	resolution inside band
		Allowed:	Quantum with a vector value and unit frequency, Hz
		Default:	'1.25Hz'

Example

nbands := 2;
for ( i in 1:nbands) {
     (fCenter.value)[i] := 88.e9;  
     (fWidth.value)[i] := 5.e8;  
     (fRes.value)[i] := (fWidth.value)[1]/4.0;   # 4 channels
}

fCenter.unit := 'Hz';
fWidth.unit := 'Hz';
fRes.unit := 'Hz';

myatm.initWindow(nbands=nbands,fCenter=fCenter,fWidth=fWidth,fRes=fRes )
