Summary M#M?1(O/NE
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 6t dI6
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight abWl ut
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. rYGRz#:~+
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 CW0UMP E5
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet MsjnRX:c3u
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally [ud|dwP"
symmetric, and does an integration over the Stray Radiation Scene. 6%? A>
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better og-]tEWA1
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer Y6VQ:glDT-
program written for this purpose. The stray spectral radiance was computed by integrating over qG9qN.|dC
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
