Abstract
We report on the results of a Markov chain Monte Carlo analysis of an inverse power law (IPL) quintessence model using the Dark Energy Task Force (DETF) simulated data sets as a representation of future dark energy experiments. We generate simulated data sets for a $\ensuremath{\Lambda}\mathrm{CDM}$ background cosmology as well as a case where the dark energy is provided by a specific IPL fiducial model, and present our results in the form of likelihood contours generated by these two background cosmologies. We find that the relative constraining power of the various DETF data sets on the IPL model parameters is broadly equivalent to the DETF results for the ${w}_{0}\ensuremath{-}{w}_{a}$ parametrization of dark energy. Finally, we gauge the power of DETF ``stage 4'' data by demonstrating a specific IPL model which, if realized in the universe, would allow stage 4 data to exclude a cosmological constant at better than the $3\ensuremath{\sigma}$ level.
