Left: comparisons of the log(g) values used as input labels of our CNN (APOGEE DR16 log(g)) with respect to log(g) values of Steinmetz et al. (2020b). We also show a residual plot and an histogram of the difference. Mean difference and scatter are indicated in the top-left corner. Middle: comparison of log(g) values trained by our CNN with respect to log(g) values of Steinmetz et al. (2020b). Right: comparison of the log(g) values derived by our CNN for 388 299 stars of our observed sample with respect to the log(g) values of Steinmetz et al. (2020b).
