 All of the above may be considered as a broad application of asteroseismic analysis of global observables. Some high-precision observations, such as those from [[http://astronomy.nmsu.edu/song-wiki/start|SONG]], will go much further than applying the scaling relations. They can provide very precise individual mode frequencies for more modes than space photometry can, including mixed modes, L=3 modes, and modes split into multiplets by internal rotation.  In fact, the relative amplitudes of the frequency multiplets can be used to measure the inclination of the stellar rotation axis {[gizon2003]}. In any case, the measured frequencies can then be confronted with the frequencies predicted from sophisticated numerical models. The result is a deeper understanding of all of the interior stellar properties and evolutionary state of stars.   All of the above may be considered as a broad application of asteroseismic analysis of global observables.
