This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 / er{sKVX<
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight $G 6kS@A
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. ^i2>Ax&T
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 K" |~D0Qgo
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet Hmk xE
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally %Y0BPTt$
symmetric, and does an integration over the Stray Radiation Scene. =cb!2%? }
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better ,3iD/8_
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer L+T'TC:
program written for this purpose. The stray spectral radiance was computed by integrating over o8H\l\(
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
