Summary a s<q
This study is a detailed follow-up to two previous studies concerning stray light in the EO-1 5
a*'N~
telescope (see EO-1 Stray Light Analysis Reports 1 and 2). Following coating of the EO-1 flight 6&xW9' 6b:
mirrors, the BRDF was measured by SSG, then re-measured by Schmitt Measurement Systems. Jj^<:t5{rN
The stray spectral radiance from the Stray Radiation Scene described in the LANDSAT 7 w3]0

specification was recalculated using the Schmitt BRDF measurements and a simple spreadsheet Ph7(JV{
calculation. This calculation assumes the Point Source Transmittance (PST) is rotationally T$8$9D_u
symmetric, and does an integration over the Stray Radiation Scene. o`y*yucHI
To refine this estimate of stray radiance, ray-trace simulations were done using TracePro to better +D{*L0$D"
predict the PST. The PST was used to calculate the stray spectral radiance using a C++ computer [2H(yLw O
program written for this purpose. The stray spectral radiance was computed by integrating over WH D/s
the LANDSAT 7 Stray Radiation Scene, weighed by the PST.
