Summary G!##X: 6'
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 MjRHA^b
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight wQf-sk#
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. DCa^

The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 = svN#q5s
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet Ix}sK"}[n
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally `}\

symmetric, and does an integration over the Stray Radiation Scene. JR|ck=tq
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better 372rbY
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer &-w
Cvp7
program written for this purpose. The stray spectral radiance was computed by integrating over >:!5*E5?
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
