Welcome to LightCone7, a flexible tabular cosmological calculator for the history and the future of expansion of the universe. Lightcone is based on the standard LCDM cosmic model. You specify the range and number of steps of a table and it gives you times and distances of the cosmic expansion history and/or future in that range. The calculator has various input data-sets to choose from, but the values can be adjusted as the user requires.
If you adjust the values T_H0, T_H∞, Seq or Ω by any appreciable amount, you will be calculating for a different universe, not necessarily ours. It is best to leave them at one of the two default (WMAP or Planck) values for now, otherwise you may get results that are difficult to understand. You may want to play around with various stretch (S) ranges for your output table, though.
Further, the user can select various sets of output columns to tabularize over ranges of redshift (or Stretch) values. For more information, hover over the ? circles (tooltips) on the calculator. There is also a short user guide available at this Wiki.
