Finding the brightest pixel#
How to find and overplot the location of the brightest pixel.
import matplotlib.pyplot as plt import numpy as np import astropy.units as u import sunpy.map from sunpy.data.sample import AIA_171_IMAGE
We start with the sample data.
aia = sunpy.map.Map(AIA_171_IMAGE)
To find the brightest pixel, we find the maximum in the AIA image data then transform that pixel coordinate to a map coordinate.
Let’s now plot the results.
