NRAO Home > CASA > CASA Toolkit Reference Manual

atmosphere.getN2OLinesOpacity - Function

4.1.1 get the integrated N2O Lines Opacity along the atmospheric path for channel nc in spectral window spwid

Description

Get the integrated N2O Lines Opacity for one channel in a band.

Arguments


Inputs
nc	Channel number (0-based; defaults to reference channel)
	allowed:	int
	Default:	-1
spwid	Int standing for spectral window id (0-based). The value must be >= 0.
	allowed:	int
	Default:	0

Returns
double

Example

nb = 1
fC = qa.quantity([850.0], ’GHz’)
fW = qa.quantity([0.5], ’GHz’)
fR = qa.quantity([0.5], ’GHz’)
at.initSpectralWindow(nb, fC, fW, fR)
print "Total N2O Lines Opacity at ", fC[’value’][0], fC[’unit’],\
" for 1.0 air mass: ", at.getN2OLinesOpacity()
