Summary S?_ ;$Cn
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 X pd^^
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight ?pv}~>
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. L?n*b
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 ]OOL4=b
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet VJeN
m3WNb
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally JOIbxU{U_
symmetric, and does an integration over the Stray Radiation Scene. '
cl&S:
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better 8y{<M"v+/
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer Gm.n@U p
program written for this purpose. The stray spectral radiance was computed by integrating over vWwnC)5
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
