Primary, specific conclusions
The DANTE radiation temperature tends to be higher than the witness
plate’s, especially when the pointing is small. (i.e. the beams are relatively
near the LEH.)
This difference can be big (~15eV).
The main exception is with low albedo and deep pointing.
Then the witness
plate radiation temperature can actually be somewhat higher than DANTE’s.
The witness plate incident spectrum is always harder than the DANTE
The LEH lip makes both temperatures higher, but the DANTE temperature
gains more than the witness plate temperature (typically 10 eV vs 5 eV).
Witness plate albedo has little effect on the overall results (~1 eV).
