Palomar 8 / C1838-198 RA: 18:41:29.9 DEC: -19:49:33 (J2000) (Most recent updates: Membership probability flag - 2024; Remaining data - July 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 Armandroff (1988) obtained CCD images in the V,R,I bands to compare the CM diagram of Pal 8 with that of 47 Tuc. He found that the HB of Pal 8 lies entirely redward of red edge of the instability strip, characteristic of a metal rich cluster. It does not extend as far to the blue as the red HB of 47 Tuc. ========================================================================= References Armandroff, T.
