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. The value must be > 0.

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

allowed:

doubleGHz

Default:

0.64

fRes

GHz

resolution inside band - Quantum with a vector value and unit frequency, GHz. Default is for a single frequency.

allowed:

doubleGHz

Default:

0.0

Returns
int

Example

 
 
nb = 1  
fC = qa.quantity(88., ’GHz’)  
fW = qa.quantity(0.5, ’GHz’)  
fR = qa.quantity(0.5, ’GHz’)  
at.initSpectralWindow(nb, fC, fW, fR)  
 
nb = 2  
fC = qa.quantity([88., 90.], ’GHz’)  
fW = qa.quantity([0.5, 0.5], ’GHz’)  
fR = qa.quantity([0.125, 0.125], ’GHz’)  
at.initSpectralWindow(nb, fC, fW, fR)
