SkyAnnulus

class gdt.core.plot.plot.SkyAnnulus(x, y, radius, width, ax, flipped=True, frame='equatorial', color='C0', alpha=1.0, **kwargs)

Bases: PlotElement

Plot an annulus on the sky in equatorial, galactic, or spacecraft coordinates.

Parameters:

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

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

• radius (float) – The radius in degrees, defined as the angular distance from the center to the middle of the width of the annulus band.

• width (float) – The width onf the annulus 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’

• color (str, optional) – The color of the annulus.

• alpha (float, optional) – The opacity of the annulus.

• **kwargs – Other plotting options

Attributes Summary
