Linear absorption coefficient times the sample radius, μR
(dimensionless). Only present for type = 'cylinder-hewat'. It is
normally entered as a known, fixed value, since it is strongly
correlated with the displacement parameters and the scale. The Hewat
expansion is validated to four decimals for μR ≲ 1.5; larger values
are still computed but emit a warning.

Active absorption correction type. One of none (no correction) or
cylinder-hewat (cylindrical Debye–Scherrer, Hewat model). Use
experiment.absorption.show_supported() to list the types available for
the current experiment. This category is available for
constant-wavelength Bragg powder experiments.
