  1. The first column is the actual coverage percentage for the BM posterior 95 % CI (how many of the GPS observations were actually covered by the 95 % CI from our BM trained without it). The last three columns contain the cross-validation root mean squared errors (CV-RMSE) in kilometers (km) from our BM approach, the conventional method [1], and linear interpolation
