Summary 8P^I TL z%
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 @ zs'Y8
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight U}6.h&$
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. *Ao R==:ya
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 QW $ G
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet zm]aU`j
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally a:"Uh**
symmetric, and does an integration over the Stray Radiation Scene. !lf|7
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better 0~ZFv Wv
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer b iSz?DJ>
program written for this purpose. The stray spectral radiance was computed by integrating over eoai(&o0$
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
