26. Conclusions

The tip of the red giant branch (TRGB) method is as precise and as accurate as the Cepheid PL relation. Moreover, an extremely useful feature of the TRGB method is that it is applicable to any galaxy containing a detectable population of old, metal-poor, low-mass stars. In practice, this means that nearly all nearby galaxies, regardless of Hubble type and/or inclination, can now be placed on a common distance scale out to the crowding and the flux limits of CCD detectors and telescopes. These distances will allow, for the first time, a complete sample of accurate, uniformly-measured distances to all galaxies within the Local Group and out to distances of ~ 10 Mpc.
