  In this work, we have gone one step further from the study presented in the
first CoRoT symposium. Our analysis consists on constructing a model database
covering the entire uncertainty box of the $\delta$ Sct star HD174966, derived
from the usual observables ($\mathrm{T}_{\mathrm{eff}}$, $\log g$ and [Fe/H]),
and constraining the models representative of the star. To do that, we use the
value of the periodicity (related to $\Delta\nu_{\ell}$) found in its CoRoT
pulsating spectrum.
