The independent variable of the derivative. Accepted options are "density",
"nuclide_density", and "temperature". A "density" derivative will give the
derivative with respect to the density of the material in [g / cm^3]. A
"nuclide_density" derivative will give the derivative with respect to
the density of a particular nuclide in units of [atom / b / cm].
"nuclide_density" derivative will give the derivative with respect to the
density of a particular nuclide in units of [atom / b / cm]. A
"temperature" derivative is with respect to a material temperature in units
of [K]. The temperature derivative requires windowed multipole to be
turned on. Note also that the temperature derivative only acconuts for
resolved resonance Doppler broadening. It does not account for thermal
expansion, S(a, b) scattering, resonance scattering, or unresolved Doppler
broadening.
