This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 mKe6rEUs|
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight 7He"IJ
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. "rn
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 n{4 iW_/D
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet o!BCR:
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally \XB,)XDB
symmetric, and does an integration over the Stray Radiation Scene. A5Jadz ~
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better HKJCiQ|k
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer 9Ad%~qciY
program written for this purpose. The stray spectral radiance was computed by integrating over \7LL neq
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
