atmosphere.getTrjSkySpec - Function

4.1.1 Returns the Rayleigh-Jeans Temperatures on each channel of a band


Description

Gets the Rayleigh-Jeans Temperatures in a spectral window spwid for Water Vapor Column wh2o, the current Air Mass, and perfect Sky Coupling to the sky.

Example

 
sw=at.getWetOpacitySpec()  
# returns a tuple of  
# 0 - The number of channels, and  
# 1 - the Equivalent Blackbody Temperatures in a band  
sw[1][’value’]  
# [34.687910103670511,  
#  35.496193465331679,  
#  36.460355664151791,

#  39.593561594172662,  
#  40.528694048924017]  
 
sw[0]  
# 8  
 
Another example:  
for s in range(at.getNumSpectralWindows()):  
        print "band", s  
        trjspec = at.getTrjSkySpec(spwid=s)  
        for i in range(at.getNumChan(s)):  
                print " - TrjSky %f [%s] " % (trjspec[1][’value’][i],trjspec[1][’unit’])
