Summary ^tI4 FQ>Y
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 Q$ A;Fk}-
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight qE M,~:lTn
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. /}nq?Vf
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 9 !s)52qt
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet ?gG%FzfQ/
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally q>[}JtXK
symmetric, and does an integration over the Stray Radiation Scene. 9b)'vr*Hy7
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better (/A

predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer _^`TG ]F
program written for this purpose. The stray spectral radiance was computed by integrating over rAS2 qt
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
