Summary gf&\)"
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 " iz'x-wy
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight Im<i.a

mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. kT =KxS{
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 #77p>zhY
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet :/.SrkN(A7
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally A~!v+W%vO1
symmetric, and does an integration over the Stray Radiation Scene. KeGGF]=>
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better Y*KP 1=Md
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer ac2G;}B|
program written for this purpose. The stray spectral radiance was computed by integrating over 3SeM:OYq]s
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
