Summary :I5]|pt
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 rZy38Wo
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight }V3 p <
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. [Pdm1]":(
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 _|ucC$*
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet {37DrSOa
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally +_?;%PKkuF
symmetric, and does an integration over the Stray Radiation Scene. w49Wl>M
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better Y'n TyH
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer zJ#e3o .
program written for this purpose. The stray spectral radiance was computed by integrating over ZpHT2-baVe
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
