Summary tHGK<r b
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 C }!$'C|
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight I*#~@:4*
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. ^|8cS0dK]Q
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 {ng
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet vOqYt42
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally #>233<
symmetric, and does an integration over the Stray Radiation Scene. l/TH"z(
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better HloP NE&}
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer cJqPcCq(wn
program written for this purpose. The stray spectral radiance was computed by integrating over bD r 'W
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
