Summary pOS.`rSK
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 'iL['4~.
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight sKHUf1
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. Uyi_B.:`
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 }B0V$
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet gCwg ;c-
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally [
8v)\lu
symmetric, and does an integration over the Stray Radiation Scene. Yq;S%.
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better %W`pTvF
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer %A W
program written for this purpose. The stray spectral radiance was computed by integrating over U<#i\4W
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
