Abstract
AbstractThe HIPPARCOS satellite has provided astronomy with a wonderful legacy. We now have high-quality parallaxes for some of the yellow and red giants as well as for some of the A and F main sequence standards. It is now possible to compare field giants with those in globular clusters and to resolve some of the discrepancies. Hipparcos luminosities are being compared with various existing MK calibrations and the most glaring (i.e. interesting) inconsistencies will be discussed.
