Summary s0WI93+z
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 blEs!/A`
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight jw]~g+x#$
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. >d%;+2
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 r$<[`L+6
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet 0x*L"HD
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally D<78Tm
x
symmetric, and does an integration over the Stray Radiation Scene. 2Ck'A0d
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better e4ym6q<6!
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer >fNRwmi
program written for this purpose. The stray spectral radiance was computed by integrating over eX;C.[&7;8
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
