Summary H=@KlSC ^
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 N>(w+h+
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight G QYR`;>
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. 0B( s+#s
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 Rq|6d
M6H
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet 3O,nNt;L {
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally wp@_4Iq1$
symmetric, and does an integration over the Stray Radiation Scene. x`g,>>&C
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better ulxlh8=
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer %tP*_d:
program written for this purpose. The stray spectral radiance was computed by integrating over OjhX:{"5 9
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
