Summary Zqv
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 IsVR4t]
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight I0;gTpt9
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. |QQ(1#d
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 NC YOY
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet k^#*x2b
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally ScQ9p379
symmetric, and does an integration over the Stray Radiation Scene. gc

To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better E_P,>f
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer Hq&MePl[
program written for this purpose. The stray spectral radiance was computed by integrating over 9|NF)~Q}'
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
