Summary Tq >?.bq9
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 :cTwp K
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight -Ar 3>d
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. "[ ]72PC
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 ;0++) :30V
specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet #1f8A5<
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally 8,(5Q
symmetric, and does an integration over the Stray Radiation Scene. ?Wp{tB9N0
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better 4,R1}.?BzJ
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer ^ S`c-N
program written for this purpose. The stray spectral radiance was computed by integrating over C[(Exe
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
