The Analysis of Isochrone Fitting Methods for Red Giant Branch Photometry , and Tip Red Giant Branch Distance Determination

We consider the procedure of isochrone fitting and its application to the study of red giant branch (RGB) photometry in old stellar populations. This is extended to consider the problems introduced by the inclusion of lower-magnitude regions of the Colour Magnitude Diagram (CMD). We refer especially to our previous paper Frayn & Gilmore (2002), where the… CONTINUE READING
