Comparison of MERTIS spectrometer (TIS) sensitivity

Comparison of MERTIS spectrometer (TIS) sensitivity
Comparison of MERTIS spectrometer (TIS) sensitivity measured during the recent thermal test with the pre-delivery ground calibration from 2013. The close agreement between the two curves indicates little to no loss in sensitivity after 13 years. Sensitivity represents how strongly each detector pixel responds to incoming infrared radiation.
