Summary jYp!?%!
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 4zyQ "?A~
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight ;iKLf~a a
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. aw*]b.f
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 yT7$6x
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet Fl`U{03
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally kvwnqaX
symmetric, and does an integration over the Stray Radiation Scene. hZJ~zx~
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better Dj\nsc@e3
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer m4/qxm"Dx:
program written for this purpose. The stray spectral radiance was computed by integrating over ,6>3aD1w~q
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
