pint.utils.convert_dispersion_measure

pint.utils.convert_dispersion_measure(dm: Quantity, dmconst: Quantity | None = None) → Quantity[source]

Convert dispersion measure to a different value of the DM constant.

Parameters:

  • dm (astropy.units.Quantity) – DM measured according to the conventional value of the DM constant

  • dmconst (astropy.units.Quantity) – Value of the DM constant. Default value is computed from CODATA physical constants.

Returns:

dm – DM measured according to the value of the DM constant computed from the latest values of the physical constants

Return type:

astropy.units.Quantity
