Abstract: | An accurate and extensive analysis on the present possibility of obtaining definite, unambiguous frequency-spectra solutions for multiperiodic -Scuti stars has been performed using artificial data. Some convenient photometric data sampling techniques have been adopted to produce very realistic light curves, with gaps and noise and subsequently critically analyzed. Useful suggestions about those to adopt in order to detect very low-amplitude components of the signal have been inferred.The results obtained point out the need of extensive devoted series of measurements, spread over a very long time span and also over a wide baseline of observers. |
