J/ApJ/611/270     Magellanic star clusters IR fluctuations     (Gonzalez+, 2004)

Infrared surface brightness fluctuations of Magellanic star clusters. Gonzalez R.A., Liu M.C., Bruzual A.G. <Astrophys. J., 611, 270-293 (2004)> =2004ApJ...611..270G
ADC_Keywords: Associations, stellar ; Magellanic Clouds ; Stars, giant Keywords: astronomical data bases: miscellaneous - galaxies: distances and redshifts - galaxies: star clusters - Magellanic Clouds - stars: AGB and post-AGB Abstract: We present surface brightness fluctuations (SBFs) in the near-IR for 191 Magellanic star clusters available in the Second Incremental and All Sky Data releases of the Two Micron All Sky Survey (2MASS, Cat. II/246) and compare them with SBFs of Fornax Cluster galaxies and with predictions from stellar population models as well. File Summary:

Note (1): For the Pre-SWB supercluster only, we have adopted the age of a cluster with s=7 from Elson & Fall (1985ApJ...299..211E). Note (2): In arcseconds at the distance of the LMC. Note (3): Origin of the data, defined as follows: a = Data from All Sky Data Release of 2MASS (Cat. II/246); b = Clusters added to sample from Elson & Fall (1988AJ.....96.1383E); c = Listed as IC 1665 in both van den Bergh (1981A&AS...46...79V) and Elson & Fall (1985ApJ...299..211E). Note (4): Otherwise, we have assumed E(B-V)=0.075, and E(B-V)=0.037 for the SMC (Schlegel, Finkbeiner, & Davis 1998ApJ...500..525S). Note (5): SWB classification from Searle, Wilkinson and Bagnuolo (1980ApJ...239..803S), which constitutes a smooth, one-dimensional sequence of increasing age and decreasing metallicity from from pre-SWB (very young) to SWB-VII
