Details

A set of coordinates generated from Kent distributions with the sample number n = 1000. The samples are elements of a list, 16 in total with the combination of location and spread (i.e. the kappa parameter or the Kent distribution). There are four locations: central (0°N 0°E), arctic (85°N 5°E), antarctic (85°S 5°E) and dateline (170°E 5°N), and there are four sizes: small (s, kappa = 50), medium (m, kappa = 15), large (l, kappa = 5), and extra-large (xl, kappa = 2).
