Summary CI^s~M >
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 %#C9E kr
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight %{ory5
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. ]Wtg.y6;
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 "w3%BbI x
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet DqHJ *x4
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally 8yk4#CZ
symmetric, and does an integration over the Stray Radiation Scene. o2!wz8
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better a]
7nK+N
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer @;}vK=6L
program written for this purpose. The stray spectral radiance was computed by integrating over U<<XeSp
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
