Summary [nO\Q3c|@$
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 A3VXh^y+
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight +O 2H":$
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. 9 -\.|5;:
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 -^i[
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet b42"Y,sbB
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally [J'O5"T
symmetric, and does an integration over the Stray Radiation Scene. dVh* a
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better Hp2ysU
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer VfK8')IXk
program written for this purpose. The stray spectral radiance was computed by integrating over '+6SkZ
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
