Summary ]#Cc7wa
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 RIQ-mpg~(k
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight I_5/e>9
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. CY*o"@-o5)
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 iciKjXJ:
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet hxzA1s%~
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally U?an\rv
symmetric, and does an integration over the Stray Radiation Scene. GeDI\-
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better ; PncJe5x
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer {G0=A~
program written for this purpose. The stray spectral radiance was computed by integrating over D2g/P8.<A
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
