CM diagrams by Hartwick & Hesser (1972) and by Fullton et al. (1995) show a red HB and a blue straggler sequence. ======================================================================= Data for the individual stars V1-5: Membership status, magnitudes and amplitudes listed for V1-5 are from Lloyd Evans & Menzies (1977). All of them are red variables. For V4-5, periods and variability types are from Whitelock (1986). V6 = V0819 Ara in the Moscow GCVS The data listed for V6 are from Hesser (1980) We conclude this is a field star because of its extreme brightness and because the ID chart of Hartwick & Hesser indicates that it is beyond the tidal radius listed in the 2010 update to the Harris (1996) catalogue. ====================================================== Discovery of the variable stars in NGC 6352: V1-3 = FL 1, 4, 8 Fourcade & Laborde (1966) with x,y positions and ID chart Sawyer Hogg in her 3rd catalog assigned the numbers V1-3 and stated that FL 2, 3, 5, 6, 7, 9-12 are considered field stars. V4-5 Lloyd Evans & Menzies (1973) V4=HH113 of Hartwick & Hesser (1972) V5=L36 identified in chart by Lloyd Evans & Menzies (1977) The number V4 was assigned by Sawyer Hogg (1973). At that time, L36 was considered to be a field star, but after Lloyd Evans & Menzies (1977) classified it as a probable member, it was assigned the number V5 in our electronic catalogue (Clement et al. 2001). V6 = star E of Hartwick & Hesser, ApJ 175, 77 (1972) with variability announced by Hesser (1980, IBVS 1758) The number V6 was assigned in our electronic catalogue (Clement et al. 2001). ==================================================================== References Clement, C.
