The DANTE radiation temperature tends to be higher than the
especially when the pointing is small. (i.e. the beams are relatively near the LEH.)This difference can be big (~15 eV). This
represents a difference in the incident radiative flux of almost 50%.
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
The LEH lip makes both temperatures higher, but the DANTE
temperature gains more than the witness plate temperature (typically 10 eV vs 5 eV).
