Summary MJrR[h]
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 (4EI-e*6
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight &t-kpA|EG
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. <Ok3 FE.K
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 s|ITsz0,td
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet 4H<lm*! ^
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally v9->nVc-
symmetric, and does an integration over the Stray Radiation Scene. F sryEHz
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better DFTyMB1H
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer j8` BdKg
program written for this purpose. The stray spectral radiance was computed by integrating over :,I:usW"
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
