Summary ;O,&MR{;|n
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 Y Kp@ n8A
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight S7cD}yx*[
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. yU7XX+cB7
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 eL)m(
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet [ 4IqHe
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally Y4,p_6aKJ]
symmetric, and does an integration over the Stray Radiation Scene. F8tMZ,:
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better (8o;Cm
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer XknNb{. r
program written for this purpose. The stray spectral radiance was computed by integrating over /J!hKK^k
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
