nu_coincidence.utils.plotting module

class nu_coincidence.utils.plotting.SphericalCircle(center, radius, resolution=100, vertex_unit=Unit('deg'), **kwargs)

Bases: PathPatch

Create a patch representing a spherical circle - that is, a circle that is formed of all the points that are within a certain angle of the central coordinates on a sphere. Here we assume that latitude goes from -90 to +90 This class is needed in cases where the user wants to add a circular patch to a celestial image, since otherwise the circle will be distorted, because a fixed interval in longitude corresponds to a different angle on the sky depending on the latitude. Parameters ———- center : tuple or ~astropy.units.Quantity

This can be either a tuple of two ~astropy.units.Quantity objects, or a single ~astropy.units.Quantity array with two elements.

radius~astropy.units.Quantity

The radius of the circle

resolutionint, optional

The number of points that make up the circle - increase this to get a smoother circle.

vertex_unit~astropy.units.Unit

The units in which the resulting polygon should be defined - this should match the unit that the transformation (e.g. the WCS transformation) expects as input.

Additional keyword arguments are passed to ~matplotlib.patches.Polygon
