Summary Y/QK+UMW*
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 .H*? '*
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight G <} 7vF
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. 3hp

The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 t!+%g) @
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet d!a2[2Us
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally ]~4}(\u
symmetric, and does an integration over the Stray Radiation Scene. EbHUGCMO
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better LIm$Wl1U
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer :Kt{t46)
program written for this purpose. The stray spectral radiance was computed by integrating over #t5JUi%in*
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
