Descripción
We propose the use of the break in the HII region luminosity function
(LF) as a possible refined powerful standard candle for extragalactic
distances. The invariance and high luminosity of the LF break has been
proposed in previous studies as a possible secondary standard candle,
but it is calibrated here for the first time using the LFs of NGC 925
and M 100, whose Cepheid distances have been determined in the HST
Extragalactic Distance Scale Key Project.
