Summary <g>_#fz "K
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 =c-j4xna>
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight *r:8=^C7S
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. lk6mu
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 FxM`$n~K
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet ETS Bd[
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally [NeOd77y
symmetric, and does an integration over the Stray Radiation Scene. ~;UK/OZ
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better 9S=9m[#y'
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer s,K @t_J
program written for this purpose. The stray spectral radiance was computed by integrating over 0J@)?,V-.
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
