interpolate_redshift_locations

luminet.isoradial.Isoradial.interpolate_redshift_locations(redshift)

Calculates which location on the isoradial has some redshift value (not redshift factor)

In general, either two or zero solutions exist. A notable exception is the tip of an isoredshift, which may only touch the isoradial and not intersect, yielding only one solution.

Parameters:

redshift (float) – Redshift value

Returns:

Tuple[ndarray] – 2-tuple containing the angles and radii for the redshift value.
