Summary &["s/!O1 R
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 t!=qt *
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight {^5LolCCH
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. Io(*_3V)B
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 6UAn# d9
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet gwA+ %]
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally EZ"n3#/
symmetric, and does an integration over the Stray Radiation Scene. +jEtu[ ;
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better "jUM}@q5
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer %Tv2op
program written for this purpose. The stray spectral radiance was computed by integrating over J1s~w`,
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
