Summary rw+0<r3|K
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 .fD k5uo
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight ^D vaT9s
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. `4;<\VYCr
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 bIWcL$}4Q
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet #/1A:ig
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally to:hMd1T
symmetric, and does an integration over the Stray Radiation Scene. $I1p"6
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better
kA y. o
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer 1egryp
program written for this purpose. The stray spectral radiance was computed by integrating over .iew5.eB+
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
