- 16:1616:16, 4 August 2022 diff hist −20 CEERS-93316 The light travel distance was incorrectly stated as "16.7 billion light years" which exceeds the age of the universe, I believe this was a typo as "16.7" is actually the redshift. Using that value in Cosmocalc https://cosmocalc.icrar.org/ give a light travel time of 13.24 billion years, a distance then (Angular Diameter Distance) of 1.92 billion light years and a Comoving Radial Distance of 34 billion light years.

- 21:4321:43, 26 March 2019 diff hist −3 GN-z11 I have reworded Note 1 as the figures were misleading, the expansion is by a ratio of (z+1)=12.1 between the proper distance then and now and 32.2/13.4 is less than 4. The "light travel" distance is not involved in that calculation.
