The radiometric calibration problem • Official, current key data • Key data obtained from NASA sphere measurements • Key data obtained from spectralon measurements August 30, 2004
Official key data: orbit 5973 Problem in spectral channel 1 Why? What happened?
NASA sphere key data: orbit 5973 Deviation is somewhat larger… no improvement…
Spectralon key data: orbit 5973 Deviation comparable to official key data… so no improvement…
