Summary `nd#< w>
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 ,<uiitOo
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight <|KK v5[
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. &;6|nl9;
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 <
"L){$
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet jV,(P$ 5;
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally Sy+]SeF&
symmetric, and does an integration over the Stray Radiation Scene. Y{Y;E Y4
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better +E q~X=x
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer "Cyo<|
program written for this purpose. The stray spectral radiance was computed by integrating over @yU!sE:
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
