Summary dya]^L}fL
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 ZKzXSI4
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight j!q5 B c?
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. h>-JXuN
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 &dF$:$'s
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet x| i"x+o
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally #gq4% ;
symmetric, and does an integration over the Stray Radiation Scene. Q}FD u,
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better i# $9>X
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer LI_>fuv"8
program written for this purpose. The stray spectral radiance was computed by integrating over Mz T#1~
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
