J/A+A/383/398       Cepheids multiphotometry                  (Paturel+, 2002)

Calibration of the distance scale from galactic Cepheids: I. Calibration based on the GFG sample. Paturel G., Theureau G., Fouque P., Terry J.N., Musella I., Ekholm T. <Astron. Astrophys. 383, 398 (2002)> =2002A&A...383..398P
ADC_Keywords: Stars, variable; Photometry, UBVRIJKLMNH Keywords: galaxies: distances and redshift - galaxies: stellar content - cosmology: distance scale Abstract: New estimates of the distances of 36 nearby galaxies are presented based on accurate distances of galactic Cepheids obtained by Gieren et al. (1998ApJ...496...17G) from the geometrical Barnes-Evans method. The concept of ``sosie'' is applied to extend the distance determination to extragalactic Cepheids without assuming the linearity of the PL relation. Doing so, the distance moduli are obtained in a straightforward way. The correction for extinction is made using two photometric bands (V and I) according to the principles introduced by Freedman & Madore (1990ApJ...365..186F). File Summary:
