Abstract
The scale covariant theory of gravity admits the possibility of a time varying
gravitational constant but contains a gauge function for which there is no independent equation.
The circumstances under which explicit forms for a gauge function may be derived within the
context of Friedmann-Robertson-Walker cosmological models are investigated and several forms
are derived.
