I The error bars of redshift drift

  1. Jul 25, 2017 #1
    Dear all,

    I am reading the paper "Cosmic dynamics in the era of Extremely Large Telescopes " by Liske et al. about redshift.
    I get the physical meaning of redshift drift, but when it comes to the error bars, I am confused.
    - Aren't the error bars given in equation (15) ?
    - Isn't this function plotted in figure 7 with S/N=13000 and N=10 ? (the red solid line??)
    - If so, then why am I getting something different while plotting it? Is there something I am missing?
