## Cosmology Calculator

This cosmology calculator uses the program cosmic to calculate a number of parameters for an object at a redshift *z*, using the given ΛCDM cosmology. The output of cosmic is shown below the form. Please note that small differences between distances given here and using other cosmology calculators are due to differences in numerical integration, e.g. Romberg vs. midpoint, and whether the contribution from the energy density of radiation is included (it is not included here).
