Summary o{?R z3z
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 g,] GzHV1
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight A{Dy3tm=
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. Ny2. C?2
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 @m+2e C77
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet HS
>B\Ip"
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally YwnYTt
symmetric, and does an integration over the Stray Radiation Scene. 0S71&I$u]
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better ~duF2m 72
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer vkE a [7
program written for this purpose. The stray spectral radiance was computed by integrating over ee\QK,Q V
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
