Terzan 3 / C1625-352 (Updated July 2016) RA: 16:28:40.08 DEC: -35:21:12.5 (J2000) ============================================================ Bytes Format Explanation 1-8 A8 Star ID 10-32 A11,1x,A11 Position 34-35 A2 Units for position R0 denotes RA, DEC in the J2000 coordinates R5 denotes RA, DEC in the 1950 coordinates XA denotes X, Y in arcseconds XP denotes X, Y in pixels 37-44 F8.4 Period (days) 46-51 F6.3 Mean magnitude (or maximum magnitude if "max" is indicated in the remarks column) 53-57 F5.3 Light amplitude (range of variability) 59 A1 Colour for mean magnitude and amplitude e.g. B, V, R, I, J, K or P (for photographic). 61-65 A5 Type of variable (draft 2006 GCVS classifications) CST denotes non variable stars previously designated as variables 67-80 A19 Notes and Remarks (f denotes field star) "--" or "----" indicates no data available ========================================================================= ID Position Period ampl C Type Notes/ RA/X Dec/Y Units Remarks ========================================================================= No known variables ======================================================================== Supplementary Notes Terzan 3 is a low concentration cluster projected on the outskirts of the Galactic bulge. A near infra-red CM diagram (K, J-K) by Valenti et al. (2007) shows a red clumpy HB indicative of a moderately high metallicity. They used their data to derive a photometric [Fe/H] = -0.82. This is in good agreement with the value [Fe/H]= -0.75 that Cote (1999) derived by measuring the equivalent width of an FeI spectral line in a few red giants. ======================================================================== References Cote, P. 1999, AJ, 118, 406 Valenti, E., Ferraro, F.
