Something about CRISM 'MTRDR' data's Browse Products

I noticed that the value range of MTRDR data’s Browse Products is 0-255. So most of the Summary products that extract from the CRISM data are vey small. In my opinion i think the finall summary products may normalized to 0-255 or other  treatment methods(For example ,convert original float 32 images to uint 8 images) which i don‘t know. So i want to know what happened. In addition,what is the difference between this processed Browse Products and the original summary products data? What is it’s advantage? Thank you very much!

Hi: I am the PDS Geosciences Node Manager and CRISM Team Member. The browse products are byte images and just meant for visual examination. The summary products generated are floating point images that are based on the algorithms shown in the CRISM Software Specification Document. I suggest you read about these products in that document, which is posted on our web site. https://pds-geosciences.wustl.edu/mro/mro-m-crism-2-edr-v1/mrocr_0001/document/crism_dpsis.pdf
