RadialPaths

Centre-conditioned radial profiles for irregular structures.

RadialPaths defines radial position from a connected support and supplied centres, then applies that geometry to any registered scalar field. It is aimed at astronomers working with irregular galaxies, mergers, tidal structures, clump complexes, resolved populations, and spatially resolved kinematics.

from radialpaths import build_geometry, radial_profile

geometry = build_geometry(mask, centres)
brightness = radial_profile(image, geometry, coordinate="rho_D")
velocity = radial_profile(velocity_map, geometry, coordinate="rho_X")
