Keywords: stars: oscillations - Cepheids - Magellanic Clouds
Description:
The radial velocity and light curves of 24 Cepheids in the Magellanic
Clouds, with period in the range 30-134d, were Fourier decomposed
with the aim of detecting resonance effects between pulsation modes.
The Tables contain the list of stars, the details of the analysis and
the Fourier parameters.
