I know at least two students who work with night-lights for ther
Master's Thesis. I'll forward them this e-mail.
If it's worth anything, a related add-on:
Inter-calibration has been an important subject for the DMSP OLS
instruments. Would be nice to learn more about newer developments, and,
if possible, expand the addon.

The add-on, given we mean the same one, is complete in the sense that the three
main models, integrated there-in, do what they intend to do. Up until someone
identifies any errors :-).
Any kind of assistance would, then, be more than welcome.
