Abstract
The coordinates of Berkeley 73 typed in the paper are wrong. The correct ones are J2000 $\alpha = 06^{\rm h}22^{\rm m}05^{\rm s}$ , $\delta = -06^{\circ}18'59''\, (l=215.26^{\circ}$ , $b=-9.39^{\circ})$ . The coordinates in the Galaxy were revised to X=-13.5 kpc, Y=-3.9 kpc, Z=-1.1 kpc, and the distance from the Galactic center $R_{\rm GC} = 14.1$ kpc. We confirm that the cluster images and colour-magnitude diagrams shown in the paper are indeed from Berkeley 73.
