SGLI relative spectral response model basing the SGLI specification
(JAXA/EORC, Aug. 2010)
This model is made for pre-launch algorithm tests.
They will be replaced after the SGLI flight model tests.

RSR=exp( log(1/2) * (abs(wl-CWL)/(HW/2))^ex )
   wl: sample wavelength, 300-1050, 900-2400, or 10000-13000nm
