Theoretical isochrones in the Beijing-Arizona-Taipei-Connecticut (BATC) filters Uabcdefghijkmnopt

Note (Jan 2, 2006): the BATC isochrones and BC tables, previously separated into 2 different sets (isoc_batc1 and isoc_batc2), were unified in into a single and more convenient set (the present isoc_batc).

The present directory (isoc_batc) contains the data files for the BATC filters Uabcdefghijkmnopt. This is a preliminary release, not yet described in papers. Anyway, before downloading, it will be useful to give a look at:

  • Paper I, that describes how bolometric corrections are computed, and gives an overview of the available isochrones: Theoretical isochrones in several photometric systems I. , by L. Girardi, G. Bertelli, A. Bressan, C. Chiosi, M.A.T. Groenewegen, P. Marigo, B. Salasnich, and A. Weiss, 2002, Astronomy & Astrophysics, 391, 195.
  • Some nice BATC papers: Yan et al. (2000) describes the calibration of the BATC survey, and Wu et al. (2005) applies the present BATC isochrones to the open cluster M48.
  • The Reference table with a summary description of the stellar evolutionary models in use, and their basic references. This allows you to know the differences between the several isochrone files (and better than the minimal table you see below).
  • The readme.txt file (ascii file, 13 Kby), with a field-by-field description of all files in the database.
    • Here you can download the (gzipped) data files:
