This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 >A7),6
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight (zCas}YAKI
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. n,bZj<3t
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 \[% [`m
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet O}*[@uv/
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally .3Jggp
symmetric, and does an integration over the Stray Radiation Scene. xoA\^AA
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better O\q|b#q}/
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer X0 *
y8"
program written for this purpose. The stray spectral radiance was computed by integrating over XuVbi=pN.2
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
