Summary pjX= :K|
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 C}pm>(F~
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight rhy-o?
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. LiV&47e*>
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 _@!vF,Wcf
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet N0-J=2
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally @ci..::5
symmetric, and does an integration over the Stray Radiation Scene. VXWV Pj#
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better Q}OloA(+
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer .=TXi<8Brw
program written for this purpose. The stray spectral radiance was computed by integrating over !C05;x8{
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
