Summary r6:nYyF$)v
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 V<n#%!M5gV
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight D/2 ;b;-
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. D_w<igu!3
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 |Y+[_D}
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet e Q#"-i
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally Pn }oSCo
symmetric, and does an integration over the Stray Radiation Scene. 3/su 1M[
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better Xlwy D
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer T(kG"dz
program written for this purpose. The stray spectral radiance was computed by integrating over w/fiNY5FZ
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
