Comparison of proper motions from timing and Gaia measurements for 11 pulsars in common. Top: Right ascension. Bottom: Declination. The error bars represent the formal uncertainties quoted from the published data, usually corresponding to a confidence level of 68%. Different marks are used to distinguish pulsars whose timing solutions were referred to different ephermerides, that is, blue filled triangles for DE200, green crosses for DE405, purple filled inverted triangles for DE421, yellow filled squares for DE430, and red filled circles for DE436.
