Opacity Tables

For historical reasons, stellar structure codes have been using the opacity tables from OPAL. However, after the first release of its opacities in 1995 [1] dedicated to stellar enveloppe conditions, The Opacity Project (OP) [2] pursued the work of atomic calculations and extended the different databases (TipTopbase). Finally the OP released in 2004 [3] the new set of monochromatic opacities available on the present site under Opacity Project (OPCD3.3). In order to simplify the work of stellar modelers, we now provided this set of tables fully compatible with the OPAL routine.
