Of the eight bands, three bands are visible light, one band is panchromatic, three bands are infrared, and one band is thermal infrared.
Band Gain - The band gain condition detected at the start of a WRS scene. H indicates band acquired in high gain mode. L indicates band acquired in low gain mode.
Bit - A single digital unit of information.
Bit Error Rate - The fraction of a sequence of message bits that are in error (a bit error rate of 10-6 means that there is an average of one error per million bits).
Browse data - A reduced data volume representation of an image scene that can be viewed to determine general ground area coverage and cloud coverage. Browse data typically consist of three spectral bands.
