Summary vgNrHq&2q
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 ]w-W
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight $S?xB$
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. i(# Fjp
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 voP#}fD
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet V^;lg[:
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally Y!(w. G
symmetric, and does an integration over the Stray Radiation Scene. XTb.cqOC
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better JNvgUb'U
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer b'/:e#F
program written for this purpose. The stray spectral radiance was computed by integrating over `'(@"-L:7
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
