Summary rb@[ Edj
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 Uu8ayN j
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight sg-^ oy*^
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. 7]Qxt%7/>
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 5JaLE 5-
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet h-"q <eY"
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally ':}9>B3 S
symmetric, and does an integration over the Stray Radiation Scene. h-Y>>l>PW0
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better 7L/LlO/
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer uQbag]&j
program written for this purpose. The stray spectral radiance was computed by integrating over pjS##pgVq
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
