Summary ~ a>S#S
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 p|s2G~0<
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight Re\o
v x9
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. l]u7.~b
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 [)k2=67
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet r"[L0Cbb
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally "MTq{f2?
symmetric, and does an integration over the Stray Radiation Scene. wNR=?Z~
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better qu!<lW~c
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer EGEMZCdk2
program written for this purpose. The stray spectral radiance was computed by integrating over &&*wmnWCS{
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
