Djorg 1 / C1744-330 (Updated May 2014) RA: 17:47:28.3 DEC: -33:03:56 (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 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 Valenti, E., Ferraro, F.
