Top: proper motion as a function of J magnitude for WISE J0725−2351, nearby WDs, and sdF/sdG subdwarfs. Bottom: tangential velocities based on the photometric distance estimate for WISE J0725−2351 (Sect. 7) and the trigonometric parallaxes of all other objects (same objects and symbols as in Fig. 1). For clarity, the error bars are shown for WISE J0725−2351 only. The error bars of sdF/sdG subdwarfs may be even larger in cases of uncertain parallaxes, whereas for WDs they are typically comparable to the symbol size.
