Summary ,,Dwb\B}
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 S 9$* w!W
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight Z>) (yi9+
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. 26c,hPIeXY
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 b`@aiXN)+
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet >&| C

calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally O; u&>BMk
symmetric, and does an integration over the Stray Radiation Scene. q& h&GZ
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better VPB,8zb ]
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer o2FQ/EIE
program written for this purpose. The stray spectral radiance was computed by integrating over s /,wyxKd
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
