PointSource

class prose.core.source.PointSource

Point source (star)

Parameters:

• region (skimage.measure.RegionProperties, optional) – An skimage RegionProperties containing the source, by default None. Only one of ‘coords’ or ‘region’ must be provided

• coords (array, optional) – Pixel coordinates of the source, by default None. Only one of ‘coords’ or ‘region’ must be provided

• peak (float, optional) – maximum pixel value of the source, by default 0

• i (int, optional) – index identifier of the source, by default None

elliptical_aperture(r[, scale])	photutils.aperture.EllipticalAperture centered on the source
fit_isophotes([debug])	Fit a photutils.isophote.Ellipse to the source.
plot([radius])	Plot circle centered on source
plot_circle(radius[, c, ax, label, fontsize])	Plot a circle centered on source
plot_ellipse([a, c, ax, label, fontsize])	Plot an ellipse centered on source, with semi-major/minor length defined by the source itself
