Data reduction and astrometry strategies for wide-field images: an application to the Capodimonte Deep Field
J. M. Alcala', M. Radovich, R. Silvotti +4
The Capodimonte Deep Field (OACDF) is a multi-colour imaging survey on two 0.5x0.5 square degree fields performed in the BVRI bands and in six medium-band filters (700 - 900 nm) wi…
Theoretical models for classical Cepheids. VIII. Effects of helium and heavy elements abundance on the Cepheid distance scale
G. Fiorentino, F. Caputo, M. Marconi +1
Previous nonlinear fundamental pulsation models for classical Cepheids with metal content Z <= 0.02 are implemented with new computations at super-solar metallicity (Z=0.03, 0.04)…
Calibration of the distance scale from galactic Cepheids:II Use of the HIPPARCOS calibration
G. Paturel, P. Teerikorpi, G. Theureau +3
New estimate of the distances of 36 nearby galaxies is presented. It is based on the calibration of the V- and I-band Period-Lumi- nosity relations for galactic Cepheids measured b…
Calibration of the distance scale from galactic Cepheids: I Calibration based on the GFG sample
G. Paturel, G. Theureau, P. Fouque +3
New estimates of the distances of 36 nearby galaxies are presented based on accurate distances of galactic Cepheids obtained by Gieren, Fouque and Gomez (1998) from the geometrical…
