The tip of the red giant branch (TRGB) is an important standard candle for determining luminosity distances. Although several 10 ^5 small-amplitude red giant stars (SARGs) have been discovered, variability was previously considered irrelevant for the

We investigate the absolute calibration of the tip of the red giant branch (TRGB) in the Small Magellanic Cloud (SMC) using small amplitude red giant stars (SARGs) classified by the Optical Gravitational Lensing Experiment (OGLE). We show that all st
