ASD Full Range Spectroradiometer Jump Correction

Correct jumps between VNIR-SWIR1-SWIR2 channels of ASD Spectroradiometers

Uses empirical correction coefficients to correct for temperature related radiometric inter-channel steps occurring in spectral data collected by Analytical Spectral Devices (ASD) spectroradiometers.

Note: This code may fail is the inter-channel steps are caused by field of view inhomogeneities rather than thermal effects! It is only designed to deal with thermal effects. For details see the discussion section in our paper.
