Summary 34/]m/2NZK
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 (= S"Kvb~#
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight BXQ\A~P\
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. =DeHxPv}f
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 t~+{Hr) #y
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet /Bg6z m
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally =!1-AR%.^
symmetric, and does an integration over the Stray Radiation Scene. 0~PXa(!^K
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better 1NE!=;VOl
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer y^E F<<\
program written for this purpose. The stray spectral radiance was computed by integrating over "z{_hp{T^
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
