Plotting radial slices
This example shows how to plot slices of constant radial distance 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.
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. The first line will give us a horizontal errorbar underneath the plots. The second line is the index to select for the radial slice.
cbar_kwargs = {"orientation": "horizontal"}
r_idx = 139
Plot the slices
fig, axs = plt.subplots(ncols=3, tight_layout=True)
ax = axs[0]
model["vr"].plot_radial_cut(r_idx, ax=ax, cbar_kwargs=cbar_kwargs)
model["br"].contour_radial_cut(r_idx, levels=[0], ax=ax, colors="white")
ax = axs[1]
model["rho"].plot_radial_cut(r_idx, ax=ax, cbar_kwargs=cbar_kwargs)
model["br"].contour_radial_cut(r_idx, levels=[0], ax=ax, colors="white")
ax = axs[2]
model["br"].plot_radial_cut(r_idx, ax=ax, cbar_kwargs=cbar_kwargs)
model["br"].contour_radial_cut(r_idx, levels=[0], ax=ax, colors="black")
plt.show()
