Summary %tMx48'N
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 1<t J3>Xl
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight vc :%
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. [j}JCmWY
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 Gp{,v
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet [!De|,u(^
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally v \[+
symmetric, and does an integration over the Stray Radiation Scene. %q}[ZD/HD
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better * bd3^mP
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer <.mH-Y5i
program written for this purpose. The stray spectral radiance was computed by integrating over 6`@b@Kd
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
