Summary yI^7sf7k
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 B&<P >AZ
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight 69`*u<{PC
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. yJ ;Qe_up
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 &=XK:+
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet tYhco V
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally p6r yUJc6
symmetric, and does an integration over the Stray Radiation Scene. Mq_P'/
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better s'bTP(wl9
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer p1W6 s0L
program written for this purpose. The stray spectral radiance was computed by integrating over Y~?Z'uR
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
