Content
-------
The abundance file is a reformatted version of the file from the
Nuclear Wallet cards, as retrieved from Brookhaven National
Laboratory. The abundances are given for all stable isotopes.


Format
------
Each record of the file contains: 

   Z        : charge number
   A        : mass number
   El       : element symbol
   abundance: abundance
   unc      : uncertainties in abundance

The corresponding FORTRAN format is (5,'(2i4,1x,a2,f11.6,2x,f8.6)')
