Effects of Photometric Errors on the Cosmological Parameters

Stuart Mufson and Nick Mostek have performed a series of Monte Carlo simulations to calculate the effect of photometric errors on the observed cosmological parameters. The code was taken from Alex Kim's IDL script systematic.pro and ported to the Minuit (ROOT) environment. Our results are posted below in Microsoft Word and PDF format. Links to the graphical results (GIF images) are also posted below.
