redshiftFromVelocity

Callable


  • Convert a radial velocity in km/s to redshift using an explicit velocity convention. Positive values indicate recession and negative values indicate approach.

    Radio velocity is a spectroscopic convention rather than a physical velocity; its domain only requires the velocity to stay below c so that the corresponding redshift is greater than -1. It therefore has no symmetric lower bound at -c.
