MACRO Science: King-Fitted Structural Parameters of 20 Globular Clusters Observed with the RLMT

Using data collected from the Robert L. Mutel Telescope, we performed g’, i’, and r’ photometry to determine the structural parameters of ~20 globular clusters, assuming King models. Our model parameters for core radius rc, tidal radius rt, and model constant k are presented and compared to the literature. Additionally, some of the targets have also been observed by Macalester’s 16-inch telescope, equipped with an SBIG CCD camera, located in St. Paul, MN. A comparison of the quality of data obtained at Macalester and those taken with the RLMT CMOS, located in Sonoita AZ, is presented.
