Introduction

Utilities to plot dispersion relations and fit modes in simulations that use the Pencil code (https://github.com/pencil-code/pencil-code).

• power.cached contains a replacement for pc.read.power that caches the results in a HDF5 file (allows faster reads and loading only a part of the array into memory)
• power.decimate.make_decimated_power allows to take the output of Pencil's power_xy subroutine and save only a subset of it into a HDF5 file. power.decimate.m_pxy_decimated is a mixin that allows the classes in read to use the decimated HDF5 output.
• power.dat2h5 converts the text files generated by Pencil's power_xy subroutine into HDF5 files.
  • powerxy_to_hdf5: converts power*_xy.dat to HDF5 files.
  • read_power: replacement for pc.read.powers.Power that uses the files generated by powerxy_to_hdf5
