Summary ( u]N
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 =) E,8L
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight ? W( 6
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. xGU(n _ Y
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 {
.*y
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet kKPi:G52F
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally hzI|A~MFB
symmetric, and does an integration over the Stray Radiation Scene. ALEnI@0
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better f>s?4
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer S.Z9$k%
program written for this purpose. The stray spectral radiance was computed by integrating over =
pI?A^
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
