Plotting equatorial slices

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

First, load the required modules.

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

import matplotlib.pyplot as plt

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_helio()
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)

Out:

['br', '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()
