Summary jOBY&W0r
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 9U2Px$E
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight K4j@j}zK9I
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. h'B9|Cm
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 DUZQO{V
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet I:F 'S#
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally $42Au2Jg
symmetric, and does an integration over the Stray Radiation Scene. _qY`KP "
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better tCZpfZ@+=
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer B ;eW/#`
program written for this purpose. The stray spectral radiance was computed by integrating over rGTWcJ
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
