SkyPolygon

class gdt.core.plot.plot.SkyPolygon(x, y, ax, flipped=True, frame='equatorial', color='C0', alpha=1.0, face_color=None, face_alpha=None, edge_color=None, edge_alpha=None, **kwargs)

Bases: PlotElement

Plot a polygon on the sky in equatorial, galactic, or spacecraft coordinates.

Parameters:

• x (float) – The azimuthal coordinate, in degrees

• y (float) – The polar coordinate, in degrees

• ax (matplotlib.axes) – The axis on which to plot

• flipped (bool, optional) – If True, the azimuthal axis is flipped, following equatorial convention

• frame (str, optional) – Either ‘equatorial’, ‘galactic’, ‘spacecraft’. Default is ‘equatorial’

• face_color (str, optional) – The color of the polygon fill

• face_alpha (float, optional) – The alpha opacity of the polygon fill

• edge_color (str, optional) – The color of the polygon edge

• edge_alpha (float, optional) – The alpha opacity of the polygon edge

• color (str, optional) – The color of the polygon. If set, overrides face_color and edge_color.

• alpha (float, optional) – The alpha of the polygon. If set, overrides face_alpha and edge_alpha.

• **kwargs – Other plotting options
