The file multiplets.dat can be read with my IDL routine read_struct, or by any
flat ascii table reader.

The top 4 lines form a simple header, that describes the content of the file,
the rest is a flat ascii table corresponding to an array of 24 columns and
5756 lines.

column  1 is nVal     - long   - order,  n
        2    lVal     - long   - degree, l
        3    freq     - double - mode frequency,                                    [uHz]

        6    nDeg     - long   - degree of the Clebsch-Gordan coefficients fit 
        7    nKept    - long   - number of m kept in the fit, after a 3-sigma rejection
