This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 ]O}e{Q>
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight T-yEn&r4)
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. %7 -(c
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 //N="9)@
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet f?ycZ
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally iO Iq2&sV
symmetric, and does an integration over the Stray Radiation Scene. _R|_1xa=
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better _'mC* 7+
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer v .*fJ
program written for this purpose. The stray spectral radiance was computed by integrating over LK4NNZf7
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
