Summary "s(|pQh;
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 6KD-nr{S
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight LZE9]Gd
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. Ol| fdQ
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 9JJ6$cLF
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet M &H,`gm
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally x;LO{S4Z
symmetric, and does an integration over the Stray Radiation Scene. B7o US}M
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better UDnCHGq
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer LW">9 ;n
program written for this purpose. The stray spectral radiance was computed by integrating over uX&h~qE/
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
