Predicted proper motions of the Crater-Leo objects. The grey plus symbol and magenta minus symbol represent the predictions obtained with the negative h+ and positive h− circulation about the northern pole, respectively. The blue crosses represent the measured proper motions from Gaia DR3 with their uncertainties and the orange crosses represent the proper motion measurements from HST. The corresponding contours correspond to the 34%, 68%, and 95% confidence levels for the 2D distribution of the proper motion parameter space.
