Summary ^E>}A
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 jk) U~KGcg
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight IN_GL18^MV
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. 3fpX
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 }P^{\SDX

To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better n Q8 EV>j2
