Summary 0N;%2=2_E
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 ~F!,PM/
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight e,0-)?5R
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. l dqLM
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 C vDxq:x
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet UvJ; A
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally + ula gE|7
symmetric, and does an integration over the Stray Radiation Scene. "rhYCZ B
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better -c *\o3)
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer I G ~`i I
program written for this purpose. The stray spectral radiance was computed by integrating over M 4yI`dr6
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
