(1997, MNRAS 284, 692) shows a blue HB. Cailliatte, (1962, Lyon Publ 5, No. 33) listed the 1950 positions for 9 red variables discovered in the vicinity of HP1 and published I magnitudes, amplitudes, periods and spectral types for them in 1964 (Haute Prov Publ 7, No. 2). They were all classified as Mira variables and probably belong to the galactic field. ====================================================== Discovery of the variable stars in HP1: V1-2 = T248-T249 identified as 248, 249 in Figure 6 by Terzan (1966, Haute Provence Publ 8, No. 12 bis) V3-6 = T361-T364 identified as 361, 362, 363, 364 in Figure 1 by Terzan (1965 , Haute Provence Publ 8, No. 11) V7-10 = T126, T130, T247, T250 identified as 126, 130, 247, 250 in Figure 6 by Terzan (1966, Haute Provence Publ 8, No. 12 bis) V11-15 = T136, T137, T139, T142, T143 identified as 136, 137, 139, 142, 143 in Figure 8 by Terzan (1966, Haute Provence Publ 8, No. 12 bis) The numbers V1-15 were assigned by Sawyer Hogg (1973) in her 3rd catalogue and so we have listed them here. However, they are probably all field stars. Samus (2009 - private communication has identified them all as stars listed in the NSV catalogue. ======================================================
