Abstract:
We have assembled 560 recent measurements from the literature of
distances of Galactic globular clusters and found revised distance
estimates for 154 of the 157 clusters in the McMaster catalogue
[Harris, 2010 edition, Cat. VII/202]. We find a trough in the
X-distribution at the Galactic centre, and symmetries corresponding to
the structure of the bar. These features indicate a distance,
R0=7.4±0.2(stat)±0.2(sys)kpc, only a little higher than Bica et
al.'s (2006, Cat. J/A+A/450/105) estimate.
