Summary k3\N . @\
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 98m|&7
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight S{Y zHK
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. kc,"w\ ai
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 tAX* CMW
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet *bkb-n Kw
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally IThd\#=
symmetric, and does an integration over the Stray Radiation Scene. @KG0QHyiU
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better :P ud% }'
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer n ]ikc|
program written for this purpose. The stray spectral radiance was computed by integrating over V"FQVtTx7
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
