Summary v\(2&*
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 Da"j E
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight sz9L 8f2
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. ^e W}XRI
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 B"%{i-v>**
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet qzb<J=FAU
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally iNMx"F0r
symmetric, and does an integration over the Stray Radiation Scene. JxyB(
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better as J)4ema
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer + F
dB '
program written for this purpose. The stray spectral radiance was computed by integrating over m3o,@=b
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
