Clustering of Local Group Distances: Publication Bias or Correlated Measurements? V. Galactic Rotation Constants
@article{deGrijs2017ClusteringOL, title={Clustering of Local Group Distances: Publication Bias or Correlated Measurements? V. Galactic Rotation Constants}, author={Richard de Grijs and Giuseppe Bono}, journal={The Astrophysical Journal Supplement Series}, year={2017}, volume={232} }
As part of an extensive data mining effort, we have compiled a database of 162 Galactic rotation speed measurements at R 0 (the solar Galactocentric distance), . Published between 1927 and 2017 June, this represents the most comprehensive set of values since the 1985 meta-analysis that led to the last revision of the International Astronomical Union’s recommended Galactic rotation constants. Although we do not find any compelling evidence for the presence of “publication bias” in recent decades…
