NRAO Home > CASA > CASA Toolkit Reference Manual

atmosphere.getWetOpacitySpec - Function

4.1.1 get the integrated zenith Wet Opacity along the atmospheric path on each channel of a band

Description

Getthe integrated zenith Wet Opacity along the atmospheric path on each channel in a band.

Arguments


Outputs
wetOpacity	mm-1	wet opacity for each channel in band - Quantum with a vector value and unit of mm-1
		allowed:	doublemm-1
		Default:
Inputs
spwid		Int standing for spectral window id (0-based). The value must be >= 0.
		allowed:	int
		Default:	0

Returns
int

Example

sw=at.getWetOpacitySpec()
# returns a tuple of
# 0 - The number of channels and
# 1 - an quantity array of wet opacity for each channel in band
sw[1][’value’]
# array([1.7225454913767393, 1.7204246078103735,
#        1.7188614166349163, 1.7179243635081174,
#        1.7177278069990962, 1.7184525049248152,
#        1.7204244157129918, 1.7242351137518073])

sw[0]
# 8

Another example:
for s in range(at.getNumSpectralWindows()):
        print "band", s
        for i in range(at.getNumChan(0)):
                print " - dryOpacity ", at.getDryOpacitySpec(spwid=s)[1][i], " wet Opacity/mm ",\
                      at.getWetOpacitySpec(spwid=s)[1][’value’][i]
