Abstract:
Infrared and optical absolute magnitudes are derived for the type II
Cepheids kappa Pav and VY Pyx using revised Hipparcos parallaxes and
for kappa Pav, V553 Cen and SW Tau from pulsational parallaxes.
Revised Hipparcos and HST parallaxes for RR Lyrae agree satisfactorily
and are combined in deriving absolute magnitudes. Phase-corrected J, H
and Ks mags are given for 142 Hipparcos RR Lyraes based on Two-Micron
All-Sky Survey observations. Pulsation and trigonometrical parallaxes
for classical Cepheids are compared to establish the best value for
the projection factor (p) used in pulsational analyses.
