Summary O|g!Y(
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 F|ML$
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight PXQ9P<m
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. NB yN}e
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 %A[p!U
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet 0?*I_[Y
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally dvdBRrf
symmetric, and does an integration over the Stray Radiation Scene. GLcZ=6)"'
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better `8b6

predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer 06W=(fY
program written for this purpose. The stray spectral radiance was computed by integrating over ,IvnNnl2
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
