Summary cTW3\S=
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 5v:c@n
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight k.b-> U
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. NijvFT$V1
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 FOz7W
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet EMy Med_
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally +m Plid\
symmetric, and does an integration over the Stray Radiation Scene. 4 \*!]5i
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better P[NAO>&t X
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer KtWn08D!
program written for this purpose. The stray spectral radiance was computed by integrating over
G:TM k4
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
