Ratio of the distances derived in this work (D_I, Table 4), with the average distances from Baumgardt & Vasiliev (2021, BV21, left panel) and the distances derived from parallaxes from Vasiliev & Baumgardt (2021, VB21, right panel). The vertical error bars correspond to the derived uncertainties, divided by D_BV21 or D_VB21. The distances from Vasiliev & Baumgardt (2021) are discrepant with ours only for the three closest GCs (10% for NGC 6626, and 20% for NGC 6266 and NGC 6717).
