Plotting equatorial slices

This example shows how to plot slices in the equatorial plane from a MAS model output.

First, load the required modules.

import matplotlib.pyplot as plt

from psipy.data import sample_data
from psipy.model import MASOutput

Next, load a set of MAS output files. You will need to change this line to point to a folder with MAS files in them.

mas_path = sample_data.mas_sample_data()
model = MASOutput(mas_path)

Each MAS model contains a number of variables. The variable names can be accessed using the .variables attribute.

print(model.variables)

['bp', 'br', 'bt', 'rho', 'vr']

Set parameters for plotting. This line will give us a horizontal errorbar underneath the plots.

cbar_kwargs = {"orientation": "horizontal"}

Plot the slices

ax = plt.subplot(projection="polar")
model["vr"].plot_equatorial_cut(ax=ax, cbar_kwargs=cbar_kwargs)

plt.show()
