Summary m \1VF\
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 KxGKA
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight +_P8'e%Iy
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. dG" K/|
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 ~@[(U!G
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet ]v<d0" 2
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally ^zKt{a
symmetric, and does an integration over the Stray Radiation Scene. `D4oAx d9
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better u mqLKf=x!
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer vuAQm}A4'g
program written for this purpose. The stray spectral radiance was computed by integrating over r(p wOO x
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
