Summary n7,LfO#
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 !4}Wp.
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight tWI%P&b
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. n=%D}W
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 d$PQb9Q+f
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet 2T-3rC)
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally 8C5*: x9l
symmetric, and does an integration over the Stray Radiation Scene. 0:zDt~Ju
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better ,H5o/qNU`{
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer ngl8) B
program written for this purpose. The stray spectral radiance was computed by integrating over T%@qlEmf
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
