Rotating a Map#
How to rotate a map.
import matplotlib.pyplot as plt import astropy.units as u import sunpy.data.sample import sunpy.map
We start with the sample data.
aia_map = sunpy.map.Map(sunpy.data.sample.AIA_171_IMAGE)
GenericMap provides the
method which accepts an angle. This returns a rotated map and does not
modify the original map. The data array size is expanded so that none of the
original data is lost due to cropping.
aia_rotated = aia_map.rotate(angle=30 * u.deg)
Let’s now plot the results.
