re: A method to improve color planetary imaging?
A key fact is that this would also improve infrared imaging. In most studies you are given the infrared readings in the *separate* infrared frequency ranges. Rarely are you given measurements that compare the intensity of the readings across different infrared filters.
The reason is because of this same problem of calibrating the comparison of the different filter images taken separately.
I'm saying if the readings were taken simultaneously, this would result in a significant increase in the mineralogical inferences you could make.
