remains unclear if qualitatively similar results can be expected in other conditions, with
different radiant angles or with hair, and how these relate to comfort and possibly heat strain.

The right hand y-axis indicates relative difference to Qn–scalp of NUDERad. The error-bars
indicate one standard deviation.
