BurnMan now has a Calibrant class. This class is a stripped-down version of a Material that is initialised with a params dictionary and a function to compute the pressure or volume at given conditions.
Objects derived from this class have the ability to output pressure/volume as a function of volume/pressure and temperature. The user can pass a V-T or P-T covariance matrix as an additional optional argument, in which case BurnMan will propagate the errors and output a full P-V-T or V-P-T covariance matrix.
A helper function is provided to convert from pressure calculated using one calibration into pressure calculated using another calibration of the same material.
This class is expected to be used by experimental petrologists and those interpreting high pressure experimental data.
