get sky brightness by integrating the transfer equation for each channel

Synopsis
getSkyBrightnessSpec(iopt)

Description

Get sky brightness by integrating the transfer equation for each channel.

Arguments

iopt	in	temperature type
		Allowed:	Int 1 or 2, standing for blackbody temperature or Rayleigh Jeans temperature
		Default:	1

Returns
Quantum with a Array value and dimension of temperature, K, which is the sky brightness for the given temperature type.

Example

tBandSpec1 := myatm.getSkyBrightnessSpec(iopt=1)
tBandSpec2 := test_atm.getSkyBrightnessSpec(iopt=2)
print spaste('For blackbody, SkyBrightness = ', tBandSpec1)
print spaste('For Rayleigh Jeans,  SkyBrightness = ', tBandSpec2)

For Blackbody, SkyBrightness = [value=[[1:2,]
    19.9541615 19.9439307 19.9339303 19.9246711
    19.9541615 19.9439307 19.9339303 19.9246711], unit=K]
For Rayleigh Jeans, SkyBrightness = [value=[[1:2,]
    17.9210985 17.9081171 17.895366 17.8833538
    17.9210985 17.9081171 17.895366 17.8833538], unit=K]
