Summary 5Hy3\_ +
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 >{F!ntEj
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight H9E(\)@
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. `sxN!Jj?
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 V4\560
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet j"6:A
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally w&C1=v -h
symmetric, and does an integration over the Stray Radiation Scene. m9Il\PoTq
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better o}W;Co
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer .FJj
program written for this purpose. The stray spectral radiance was computed by integrating over )-#i8?y3C
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
