Summary ,FPgbs
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 VSkx; P
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight

mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. Aq{m42EAj
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 ,uP1U@Cas
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet N7xkkAS{
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally rXz,<^Hmj
symmetric, and does an integration over the Stray Radiation Scene. $V8B =k~
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better W$Bx?}x($
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer VR oeq {
program written for this purpose. The stray spectral radiance was computed by integrating over ;G3{ e
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
