Summary / BIPLDN6
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 kcYR:;y
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight ;OKQP~^iH2
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. 7k$8i9#
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 '[-/X a['
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet k Dv)g
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally ,DE%p
+q
symmetric, and does an integration over the Stray Radiation Scene. u\E.H5u27
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better Zka;} UL&Q
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer J `mp8?;%
program written for this purpose. The stray spectral radiance was computed by integrating over rzTyHK[
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
