Period spacing patterns, as computed by GYRE and accounting for rigid rotation at the rate of HD 43317, using the traditional approximation, for two demonstrative MESA models. Left: 6.5 M_⊙ MESA model at the ZAMS; right: 4.0 M_⊙ model close to the TAMS. Each row represents the theoretical period spacing pattern for a given mode geometry, with the range of radial orders as listed. Gray boxes correspond to regions where the frequency difference between theoretical frequencies of modes with consecutive radial order is smaller than the Rayleigh frequency resolution of the CoRoT data; these ranges cannot therefore be used. The corresponding pulsation period and radial order for the limiting theoretical mode to be used in the modeling for that given MESA model and mode geometry is listed in each upper left corner.
