Summary E<tR8='F
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 "(W ;rl
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight |xZu? )M4
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. n6,YA2yZO
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 e <{ d{
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet b== jlYa=
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally (x/:j*`K
symmetric, and does an integration over the Stray Radiation Scene. -0q|AB<
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better 3O4lG e#u
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer XZ8rM 4

program written for this purpose. The stray spectral radiance was computed by integrating over OESKLjFt
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
