Name


    REDSHIFT_AXIS

Purpose


    For a plotting coordinate system that is set up in terms of
    cosmic time in Gyr, adds a redshift axis.

Category


    Astro

Calling Sequence


    REDSHIFT_AXIS, Z

Inputs


    Z: Array of redshifts at which to label axis.

Keyword Parameters


    XAXIS: XAXIS=0 for a lower x-axis, XAXIS=1 for an upper x-axis.
                  Default: XAXIS=1
    YAXIS: YAXIS=0 for a left y-axis, YAXIS=1, for a right y-axis.
                  Default: no y axis.
    H100: Hubble parameter in units of 100 km/s/Mpc. Required.
    OMEGAM: Total matter density at z=0. Required.
    OMEGALAMBDA: Total vacuum energy density at z=0. Required.
    LOOKBACK: Time is in lookback time (default is time since Big Bang).
    _EXTRA: Extra keywords are passed to AXIS procedure.

Outputs


    Displays an axis showing redshift.
