Summary XOrfs sj
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 7u11&(Lz
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight ^kj=<+ v#
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. K6\` __mLf
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 2V#6q,2
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet C77D{@SM
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally vM0_>1nN
symmetric, and does an integration over the Stray Radiation Scene. [p;*r)f2}
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better N}/>r D
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer -R+zeu(e'
program written for this purpose. The stray spectral radiance was computed by integrating over kM*T$JqN
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
