Verification of Cepheid Variable Distance Measurements Using Roxy's Ruler

Authors: Bruce Rout

There has been some controversy over the validation of using the period/luminosity relationship of Cepheid variables to measure the distance to galaxies[2]. We present here a statistical analysis of distance variations for 21 galaxies between Cepheid variables and Roxy's Ruler. The analysis shows there is no systemic error in Measurements to galaxies using Cepheid variables and that such measurements are valid within well defined degrees of error.
