Notes. The meaning is 
) and log gcorr = a + log gpubl + (blog gpubl). The values by Stassun et al. (2019) could not be checked for the log g of CP4 stars because they include an insufficient number of objects. If no values a and b are listed, the published astrophysical parameters can be used as they are. The quantity σ gives the standard deviation of the calibrated parameter from the ‘standard value’ from Ghazaryan et al. (2018, 2019) in per cent. The errors in the final digits of the corresponding quantity are given in parentheses.
