  We present a first application of Whosglad method to the components A and B
of the 16 Cygni system. The method was developed to provide a comprehensive
analysis of stellar oscillation spectra. It defines new seismic indicators
which are as uncorrelated and precise as possible and hold detailed information
about stellar interiors. Such indicators, as illustrated in the present paper,
may be used to generate stellar models via forward seismic modeling. Finally,
seismic constraints retrieved by the method provide realistic stellar
parameters.
