Not allowing for a small central obscuration from the Cassegrain secondaries. After correction for finite field of view, off axis effects, Doppler shifts, etc. On Jan. Launched in on NASA's Aura spacecraft, TES was the first instrument designed to monitor ozone in the lowest layers of the atmosphere directly from space. Its high-resolution observations led to new measurements of atmospheric gases that have altered our understanding of the Earth system.

TES collected spectral "signatures," illustrated here, of ozone and other gases in the lower atmosphere. Credit: NASA.
