Theoretical isochrones in the ESO Imaging Survey EMMI Bw,Vw,R,Rw,Iw VEGAmag system

The present directory (isoc_emmi) contain the data files for the ESO Imaging Survey EMMI Bw,Vw,R,Rw,Iw VEGAmag system. Before downloading, please give a look at:

  • The Paper preprint (gzipped postscript, 1.6 Mby) that describes the bolometric corrections: Theoretical isochrones in several photometric systems I. Johnson-Cousins-Glass, HST/WFPC2, HST/NICMOS, Washington, and ESO Imaging Survey filter sets, by L. Girardi, G. Bertelli, A. Bressan, C. Chiosi, M.A.T. Groenewegen, P. Marigo, B. Salasnich, and A. Weiss, 2002, Astronomy & Astrophysics, in press.
  • 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:
