Summary "T} HH
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 vVo# nzeZ5
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight 'NnmL M(oh
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. / $'M
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 f&X M|Bg

calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally `$/M\aM%

To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better /!y3ZzL
