"2D Fokker-Planck models of rotating clusters"

We present a comprehensive set of models of rotating clusters, which uses as entries dynamical age and presently observed flattening, and offers a limited range of applicable models in full detail and ready to download and use. Data structure and some exemplary comparison with observations are presented in Fiestas, Spurzem & Kim (2006, MNRAS, 373, p677). For the modelling techniques see Einsel & Spurzem (1999 MNRAS, 302, p81, Paper I) and Kim, Einsel, Lee, H.M. Spurzem & Lee, M.G. (2002 MNRAS 334, p310, Paper II). Kim, Lee & Spurzem (2004, MNRAS 352, 655, Paper III) presents the evolution of rotating systems with a mass spectrum.

Quick usage guide: select dynamical age and ellipticity (e.g. according to observed cluster) from menu item 3 (Time-Ellipticity Grid, table 2). There you find a selection of models. For each model data can be downloaded. Examples what kind of plots can be produced see item 5 (Plot Samples). Note: especially for clusters with small ellipticity there are many possible models.
