adrn/gala: v1.6.1

Changelog included below: New Features Added a .replicate() method to Potential classes to enable copying potential objects but modifying some parameter values. Added a new potential class MN3ExponentialDiskPotential based on Smith et al. (2015): an approximation of the potential generated by a double exponential disk using a sum of three Miyamoto-Nagai disks. The Orbit.estimate_period() method now returns period estimates in all phase-space components instead of just the radial period. Added a store_all flag to the integrators to control whether to save phase-space information for all timesteps or only the final timestep. Added a plot_rotation_curve() method to all potential objects to make a 1D plot of the circular velocity curve. Added a new potential for representing multipole expansions MultipolePotential. Added a new potential CylSplinePotential for flexible representation of axisymmetric potentials by allowing passing in grids of potential values evaluated grids of R, z values (like the CylSpline potential in Agama). Added a show_time flag to Orbit.animate() to control whether to show the current timestep. Changed Orbit.animate() to allow for different marker_style and segment_style options for individual orbits by passing a list of dicts instead of just a dict. Added an experimental new class SCFInterpolatedPotential that accepts a time series of coefficients and interpolates the coefficient values to any evaluation time. Bug fixes Fixed a bug where the NFWPotential energy was nan when evaluating at the origin, and added tests for all potentials to check for a finite value of the potential at the origin (when expected). Fixed a bug in NFWPotential.from_M200_c() where the incorrect scale radius was computed (Cython does not always use Python 3 division rules for dividing integers!). Fixed a bug in the (C-level/internal) estimation of the 2nd derivative of the potential, used to generate mock streams, that affects non-conservative force fields. API changes The Orbit.estimate_period() method now returns period estimates in all phase-space components instead of just the radial period.
