DR3 GSP-Spec logarithm of surface gravity vs. effective temperature for sources observed by the Kepler mission and included in our high-precision sample. The period spacing, ΔΠ1, derived from Kepler data (not used by the Gaia GSP-Spec module) is illustrated as a colour code, confirming the GSP-Spec parametrisation of RGB and RC giants.
