Summary (c"!0v
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 N@g+51ye
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight _~!,x.Dbp
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. ?k#% AM
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 J0IK =Y
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet hY!G>d{J
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally LBg#KQ @
symmetric, and does an integration over the Stray Radiation Scene. zv41Yv!x}
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better $a G'.0HW
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer x{m)I <.:
program written for this purpose. The stray spectral radiance was computed by integrating over VaB7)r
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
