Seismic log g VS FliPer for ∼15 000 stars observed with Kepler long-cadence observational mode (black dots). The gray, red, and blue shaded regions correspond to MS and subgiant stars, RG, and high-luminosity RG stars or AGB, respectively. White diamonds represent the weighted mean value of log g (see Eq. (2)) computed with 30 MS stars and 300 RGs each. The white area delimits the location where 68% of the stars in our sample are around the mean value. The white boundary represents the equivalent of a 1σ uncertainty (standard deviation) on the surface gravity obtained from FliPer.
