- W1534668575 abstract "A measurement of the distance to Virgo Cluster by a direct method along with a realistic error analysis is important for a reliable determination of the value of Hubble Constant. Cepheid variables in the face-on spiral M100 in the Virgo Cluster were observed with the Hubble Space Telescope in 1994 under the HST Key Project on the Extragalactic Distance Scale. This work is a reanalysis of the HST data following our study of the Galactic Cepheids (in an accompanying communication). The periods of the Cepheids are determined using two independent methods and the reasons for varying estimates are analyzed. The log(period) vs V -magnitude relation is re-calibrated using LMC data as well as available HST observations for three galaxies and the slope is found to be −3.45 ±0.15. A prescription to compute correction for the flux-limited incompleteness of the sample is given and a correction of 0 to 0.28 magnitude in V -magnitude for Cepheids in the period range of 35 to 45 days is applied. The extinction correction is carried out using period vs mean (V − I) color and V -amplitude vs (V − I) color at the brightest phase relations. The distance to M100 is estimated to be 20.4 ± 1.7 (random) ±2.4 (systematic) Mpc." @default.
