How to embed a zoomed portion of a FITS image in the same plot with APLpy

I want to embed a zoomed portion of a FITS image in the same plot with APLpy.

But when loading a FITS file with APLpy, there is only a 'FITSFigure' object returned.

fig = aplpy.FITSFigure('tmp.fits', slices=[0,0])

Is it possible to make it work with zoomed_inset_axes like here , or there are some other solution?

Solution

  • You may specify the figure to which to plot with aplpy. You can then get the axes inside the figure. 

    fig = plt.figure()
aplpyfig = aplpy.FITSFigure('tmp.fits', figure=fig)
axes = fig.get_axes()

    From that point onwards you can work with that axes and use any of the methods that matplotlib offers to obtain insets.
