This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 `$;+ g ,
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight x!7yU_ls `
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. /="HqBI#i
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 eb:A 1f4L
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet mX# "+X|
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally BR_TykP
symmetric, and does an integration over the Stray Radiation Scene. fjz) Gp
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better u:P~ j
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer 5mB]N%rfW%
program written for this purpose. The stray spectral radiance was computed by integrating over Gm8E<iTP
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
