Available photometric systems

Updated to Wed May 13 12:06:45 CEST 2009

Here follows a list of the photometric systems for which we are presently providing bolometric corrections, extinction coefficients, isochrones, and simulations of stellar populations. The list extends those you find in our papers, in particular those in Girardi et al. (2002), Girardi et al. (2005), Girardi et al. (2008), Marigo et al. (2008), Aringer et al. (2009). In a few cases (as indicated in the last column), we have also revised the zeropoints in view of new literature data. The photometric systems below are used in the following databases and web interfaces:

  • TRILEGAL: mock photometric catalogues on demand
  • CMD: theoretical isochrones on demand
  • dustyAGB07: bolometric corrections and extinction coefficients, valid for most stars
  • synphot/Cstars: bolometric corrections for C stars.
