Summary v^\JWPR/
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 1VGpq-4*j
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight !G[f[u 4Zg
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. ? -S8yqe
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 r;'i<t{P

To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better FvAb h]/4
