Summary U+qyS|i
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 z?<B@\~
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight J{^md0l
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. ^7wqb 'xg
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 LT<2 n.S
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet x;)I% c
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally X+ITW #
symmetric, and does an integration over the Stray Radiation Scene. jQ;/ =9
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better `X5!s
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer `v!.
,Yr
program written for this purpose. The stray spectral radiance was computed by integrating over BW7AjtxQ&
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
