Summary %y}l^P5z
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 a76 `"(W
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight yW)X
asn
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. =f{YwtG
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 f8?c[%br
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet \%011I4
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally G u P1
symmetric, and does an integration over the Stray Radiation Scene. +~]LvZt I_
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better -

predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer dTW3mF4=
program written for this purpose. The stray spectral radiance was computed by integrating over CN F3".a
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
