4.1.1.0 atmosphere.initSpectralWindow

atmosphere.initSpectralWindow - Function

4.1.1 initialize spectral window
Description

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

Arguments


Inputs
nbands		number of spectral windows/bands
		allowed:	int
		Default:	1
fCenter	GHz	center frequencies - Quantum with a vector value and unit of frequency, GHz
		allowed:	doubleGHz
		Default:	90
fWidth	GHz	frequency width of band - Quantum with a vector value and unit of frequency, GHz

Example

nb=1
fC=quantity(88.,’GHz’)
fW=quantity(.5,’GHz’)
fR=quantity(.5,’GHz’)
