The file cg-coefs.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 19 columns and
5756 lines.

column  1 is nVal     - long   - order,  n
        2    lVal     - long   - degree, l
        3    freq     - double - mode frequency,                                    [uHz]
        4    sFreq    - double - uncertainty on the mode frequency,                 [uHz]
     5-10    CG[*]    - double[6] - Clebsch-Gordan coefficients, k=1,6              [nHz]
    11-16    sCG[*]   - double[6] - uncertainty on CG coefs,     k=1,6              [nHz]
       17    nFit     - long   - number of m fitted 
       10    nDeg     - long   - degree of the Clebsch-Gordan coefficients fit 
       19    nKept    - long   - number of m kept in the fit, after a 3-sigma rejection
