As mentioned on Thursday's telecon it comes with a few caveats
1) raw hyperspectral data input should be from a sunny day
2) The zenith angles used in the calibration data are:
42.2996327647, 47.5769483476, 53.0208203608, 58.3649963736, 63.979258866, 75.0731481199, 80.7132317413, 86.5222038003 ;
The closer the raw data is to these angles the better the result
3) The calibration routine needs some tweaking - but indices of the form (simple ratio) ind= (A-B) / (A+B) should be OK
