NGC 7492 is a striking case because of its very small extension and its high destruction rate driven by the galaxy as computed by GO97.
NGC6254), to be similar to the cluster velocity dispersion.
Thanks to the relatively small distance of NGC 5139 and its high release of unbound stars during its current disk shocking, we estimate the mass loss to be between 0.6 and 1% of the cluster total mass, taking into account a possible mass segregation in the cluster halo.

This object is usually referred to as NGC6633 although many sky charts list NGC objects simply by their 4 digit numbers.
M9 (NGC 6333) is the smallest of this group, unresolved except in large instruments.
M62 (NGC 6266) is six degrees SW of theta Oph (and four degrees south of M19); this is another non-circular globular cluster, a little brighter than M19.
