NGC  104 For some of the stars among V29-V41, identification in SIMBAD is 
NGC  104  different
NGC 4372 X,Y from J.Kaluzny, W.Krzeminski, 1993MNRAS.264..785K
NGC 5139 The "new variable" NV310 from J. Kaluzny's web catalog is V791 Cen
NGC 5272 "Lit.", unless stated, means CVSGC position with a small systematic 
NGC 5272  correction to declination introduced
NGC 5904 The system of X,Y for V149-V154 in CVSGC is different from that for 
NGC 5904  other stars (wrong direction of the X axis)
NGC 5927 Much confusion in numbering in the literature. Identifications from 
NGC 5927  charts in 1974MNRAS.169...79M
NGC 6205 X,Y from Astr. Tsirk. 1136 are believed to be not accurate
NGC 6356 A field RR star V2000 Oph closer to the cluster than V6 but not 
NGC 6356  in CVSGC
NGC 6397 Astrometry from A&AS, 1997, 122, 1 used for V3 - V11
NGC 6441 We assume V11 = No. 4427, V12 = No. 4323
NGC 6584 If possible, coordinates from Samus et al. (1995PAZh...21..596S) 
NGC 6584  replaced with newer and more accurate ones from 2MASS
