Summary aM,g@'.=
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 v~._]f$:
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight K]7[|qf&
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. ?>vkY^/
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 wq1s#ag<
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet 8. +f@wv
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally ymqn1ja1
symmetric, and does an integration over the Stray Radiation Scene. "@5{=
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better /6n"$qon6
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer cSG(kFQ
program written for this purpose. The stray spectral radiance was computed by integrating over fLSDt(c',
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
