The Carnegie-Chicago Hubble Program. I. An Independent Approach to the Extragalactic Distance Scale Using only Population II Distance Indicators — mentioned by sanxiyn

I am very excited about Wendy Freedman's number. Her program is called CCHP(Carnegie-Chicago Hubble Program). The first paper was in 2016: https://arxiv.org/abs/1604.01788. The idea is to use only Population II stars, while Adam Riess's number uses Population I stars. If the number is in between, that's really cool.
