Summary $0^P0RAH
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 !,Zp? g)
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight ",>H(wJ8
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. iRi{$.pVJ
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 1|8<H~&
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet bw&myzs
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally oRp:B&
symmetric, and does an integration over the Stray Radiation Scene. 'lZ.j&
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better DF {OnF
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer \C5%\4
program written for this purpose. The stray spectral radiance was computed by integrating over XR0O;JN
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
