To calculate *h*, choose a value for *X*’, Look up q in *VisRad* and use the following relationship:

Side view of Halfraum

The specification of beam pointing
and focusing

R axis

The main variable in this set of calculations is *X*’. We want to see how the DANTE and witness plate radiation temperatures and their incident spectra compare to
each other as *X*’
varies every 200 microns from 200 to 800.
