The Gaia parallax discrepancy for the cluster Pismis 19, and separating Scutis from Cepheids
Daniel Majaess, Charles J. Bonatto, David G. Turner +10
Pre-Gaia distances for the open cluster Pismis 19 disagree with Gaia parallaxes. A 2MASS red clump distance was therefore established for Pismis 19 ( kpc), whic…
