Summary h3k>WNT7
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 G--X)h-
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight mOn_#2=KF
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. Jut&J]{h
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 E 8}evi
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet (A6~mi r!
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally /kkUEo+
symmetric, and does an integration over the Stray Radiation Scene. _"yA1D0d_
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better fTvm2+ .nX
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer 'EA skA] *
program written for this purpose. The stray spectral radiance was computed by integrating over wL

the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
