Drawing and using a Great Arc#
How to define and draw a great arc on an image of the Sun, and to extract intensity values along that arc.
<astropy.visualization.units.quantity_support.<locals>.MplQuantityConverter object at 0x7fb37e0abee0>
We start with the sample data.
m = sunpy.map.Map(AIA_171_IMAGE)
Let’s define the start and end coordinates of the arc.
Create the great arc between the start and end points.
Plot the great arc on the Sun.
[<matplotlib.lines.Line2D object at 0x7fb37f3a91e0>]
Now we can get the intensity along the great arc coordinates, along with the angular distance from the start of the arc
Plot the intensity along the arc from the start to the end point.
