Summary Og&2,`Jb
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 W!Xgse3
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight grS,PKH
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. kPxEGuL'
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 kt S0
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet GV2}K
<s
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally \(z)]D
symmetric, and does an integration over the Stray Radiation Scene. Jz-f1mhQV
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better i$F)h<OU+
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer 7;_5[_
program written for this purpose. The stray spectral radiance was computed by integrating over k\%{1oRA
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
