Djorg 1 / C1744-330 RA: 17:47:28.3 DEC: -33:03:56 (J2000) (Most recent updates: Membership probability flag - 2024; Remaining data - May 2014) ============================================================ Bytes Format Explanation 1-8 A8 Star ID 10-32 A11,1x,A11 Position 34-35 A2 Membership probability flag based on data published by Prudil & Arellano Ferro (2024) m1: prob >=0.85; m2: prob >=0.7 and <0.85; m3: prob >= 0.5 and <0.7; f: prob <0.5 u: no data available 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 Mem Period ampl C Type Notes/ RA Dec Flag Remarks ========================================================================= No known variables ========================================================================= Supplementary Notes This cluster lies in a crowded field near the Galactic centre. A near IR (K, J-K) CM diagram was published by Valenti et al. (2010) who estimated [Fe/H] = -1.51, based on the slope of the RGB. The CM diagram indicated an HB red clump in the general field around the cluster, but when only stars less than 20 arcsec from the cluster centre were included, it disappeared. Thus the red clump is probably due to field contamination. ======================================================================= References Prudil Z., Arellano Ferro, A. 2024, MNRAS, 534, 3654 Valenti, E., Ferraro, F.
