Question:
What are the bands and spectral ranges for Hyperion data?

Answer:
There are 220 unique spectral channels collected with a complete spectrum covering from 357 - 2576 nm. The Level 1 radiometric product has a total of 242 bands but only 198 bands are calibrated. Because of an overlap between VNIR and SWIR focal planes, there are only 196 unique channels. Calibrated channels are 8-57 for the VNIR, and 77-224 for the SWIR. The reason for not calibrating all 242 channels is mainly due to the detectors' low responsivity. The bands that are not calibrated are set to zero in those channels.
