| Abstract: |
A reanalysis of the HST data on Cepheids in the Virgo cluster spiral M100 is presented, based on our study of the Galactic Cepheids. A distance modulus of 31.49 mag is derived, which is higher than the HST Key Project value of 31.04 mag obtained from the same data earlier (Ferrarese et al. 1996). The increase in the distance is caused by nearly equal contributions from a different calibration of the slope and the zero point of the period-luminosity relation and a correction for the flux-limited incompleteness bias. |
