ABSTRACT: The graviton redshift theory (GRST) is the theory that gravitons lose energy thru gravitational redshift while traveling in the accelerating system of a gravitational field. In this report, we show that the GRST when applied to the galaxies in the Spitzer Photometry and Accurate Rotation Curves database gives reasonable fits to the rotation curves of all 175 galaxies in the database using a fixed set of parameters. Three basic parameters are involved: the baryonic Tully-Fisher relation normalization multiplier
A
gal
, the coupling constant scale
k
and the coupling constant exponent
β
. In the fitting process for all the galaxies, the tables of values for the parameters are pre-defined at the beginning, using a working set of parameter values obtained during preliminary trials, and then these values are not altered during the entire fitting procedure. The emphasis of this report will be to critique the GRST by the analysis of the fits made in terms of the distributions of masses, coupling constants and fitting errors.
