MCR-TRGB: A Multiwavelength-covariant, Robust Tip of the Red Giant Branch Measurement Method

We present a new method to measure colors and magnitudes of the tip of the red giant branch (TGRB) in multiple bandpasses simultaneously by fitting an n -dimensional Gaussian to photometry of candidate tip stars. We demonstrate that this method has several advantages over traditional edge detection,...
