Summary cL4Go,)w
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 pd: YR;
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight LHZsmUM(dg
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. hC<E 4+5.,
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 o?M ;f\Fy
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet #X*);cn
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally K-Pcew^?
symmetric, and does an integration over the Stray Radiation Scene. AdDR<IW
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better *!`&+w
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer F)eP55C6
program written for this purpose. The stray spectral radiance was computed by integrating over h0~<(3zC
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
