Summary <NX6m|DD
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 3H/4$XJB
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight Y)v_O_`
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. +D+Rf,D
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 yB^_dE
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet *e-+~/9~
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally /3v`2=b
symmetric, and does an integration over the Stray Radiation Scene. lMBXD?,,J
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better pSJc.j
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer rv97Wm+
program written for this purpose. The stray spectral radiance was computed by integrating over +~\c1|f
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
