Summary xqaw00,s
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 zy[|4Q(?
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight ktK/s!bgY
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. 1z=}`,?>
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 DZ0\pp?S
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet Vq#_/23=$y
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally !)'|Y5 o
symmetric, and does an integration over the Stray Radiation Scene. 4$b9<:M_
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better @EcY&mP)
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer DR#[\RzNI
program written for this purpose. The stray spectral radiance was computed by integrating over Q@#Gm9m
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
