Summary sa7F- XM
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 c SV`?[a
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight BidTrO
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. @MoBR.
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 'o!{YLJ fM
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet MR?5p8S#g
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally -J06H&/k
symmetric, and does an integration over the Stray Radiation Scene. Bh#?:h&f
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better H;~Lv;,g,
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer |h7 d #V>
program written for this purpose. The stray spectral radiance was computed by integrating over YV{^2)^
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
