pynbody.analysis.morphology.estimate_jcirc_from_energy(h, particles_per_bin=1000, quantile=0.99)

Estimate the circular angular momentum as a function of energy.

This routine calculates the circular angular momentum as a function of energy for the stars in the simulation, using a profile with a fixed number of particles per bin. It then estimates a circular angular momentum for each individual particle by interpolating the profile.

Parameters:

• h (SimSnap) – The simulation snapshot to analyze

• quantile (float) – The circular angular momentum will be estimated as the specified quantile of the scalar angular momentum

• particles_per_bin (int) – The approximate number of particles per bin in the profile. Default is 1000.
