abstract __init__()[source]#
abstract calculate(simulation, ion='ovi')[source]#

Calculate the ion fraction for a given ion in the gas particles of a simulation.

Parameters:

  • simulation (pynbody.snapshot.SimSnap) – The simulation snapshot to calculate the ion fractions for. The gas particles must have ‘rho’ and ‘temp’ fields.

  • ion (str) – The name of the ion to calculate the fraction for. The default is ‘ovi’. Case insensitive.

Returns:

The ion fraction for each gas particle in the simulation, according to the table.

Return type:

array-like
