Summary DnMwUykF>0
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 Sz)' ogl
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight SIF/-{i(X
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. J{p1|+h%
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 '8RsN-w
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet L3u&/Tn2
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally "/*\1v9
symmetric, and does an integration over the Stray Radiation Scene. UU YSFa %
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better axv>6 k
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer 8`q:Gz=M\
program written for this purpose. The stray spectral radiance was computed by integrating over t9k zw*U9
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
