Summary c)8V^7= Q
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 XWvT (+J
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight J_tj9+r^
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. eCB(!Y|
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 q0Fq7rWP
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet ]@OGp:Hz
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally O[Xl*9P
symmetric, and does an integration over the Stray Radiation Scene. usi v`.
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better Dt,b\6
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer }^uUw&
program written for this purpose. The stray spectral radiance was computed by integrating over E@\e37e
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
