Summary C]+T5W\"<B
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 L]HYk }oD.
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight j;b<oQH
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. n/]$k4h
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 5 Pl~ du
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet -'!%\E;5
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally ]w=6.LzO*
symmetric, and does an integration over the Stray Radiation Scene. c;e2=

To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better sZhl.[&zo
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer hq^@t6!C\m
program written for this purpose. The stray spectral radiance was computed by integrating over P>t[35 /1
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
