This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 7l7VT?<:
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight 3chx 4
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. WT\wV\P u
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 oQ,n?on
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet xp1/@Pw?
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally GDCp@%xW
symmetric, and does an integration over the Stray Radiation Scene. >h8 m8J
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better W!HjO;
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer K^o$uUBe
program written for this purpose. The stray spectral radiance was computed by integrating over "<|KR{/+
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
