Summary u|T]Ne
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 NL> Trv5
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight H(tC4'tA
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. Qe\vx1GRLH
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 W G@3+R>{
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet s^SU6P/ ]
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally {I0U 4]
symmetric, and does an integration over the Stray Radiation Scene. 09 trFj$L
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better F_9

predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer y.}{KQ"a*
program written for this purpose. The stray spectral radiance was computed by integrating over ,|3_@tUl
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
