Differences between QGeoidCOL2023 and the GPS/leveling data a before and b after applying the 7-parameter correction model, and the differences between QGEOID2021 and the GPS/leveling data c before and d after applying the 7-parameter correction model. Note that for the plots before applying the correction surface, the mean values have been removed
