calc_isoredshifts ================= .. py:method:: luminet.black_hole.BlackHole.calc_isoredshifts(redshifts=None, order=0) Calculate isoredshifts for a list of redshift values This method creates an array of `Isoradials` whose coordinates will be lazily computed. These no-coordinate isoradials are used by the `Isoredshift` to calculate the locations of redshift values along these isoradials. :Parameters: **redshifts** (*List[float]*) -- list of redshift values :returns: List[:class:`~luminet.isoredshift.Isoredshift`] -- list of calculated isoredshifts
