Abstract (from CDS):

We present V and I photometry for NGC 5986 and B and V for NGC 6712. NGC 5986 has a blue extended horizontal branch, while NGC 6712 has a composite red and blue horizontal branch, where the latter extends to unusual bluer colours. Both clusters have RR Lyrae. We derive a reddening E(B-V)≃0.29 and a distance from the Sun d≃11.2kpc for NGC 5986, and E(B-V)≃0.33 and d≃7.9kpc for NGC 6712. Their galactocentric distances of RGC=5.2 and 3.6kpc respectively, locate them in the inner halo; NGC 6712 could be considered to be located in the bulge. NGC 6712 has |z|≃500pc, indicating that the cluster is crossing the disk. We estimate metallicities of [Fe/H]=-1.6 and -1.0 respectively for NGC 5986 and NGC 6712.
