Abstract (from CDS):

Using the Hubble space Telescope Fine Guidance Sensor, we have measured the trigonometric parallax of the bright cataclysmic variable 1223 Sgr. The absolute parallax is π_abs= 1.96± 0.18mas, making V1223 Sgr the most distant CV with a well-determined trigonometric parallax. This distance, a Lutz-Kelker correction, and the previously measured extinction yield an absolute visual high-state magnitude M_V=4.0±0.2. We outline a model, which is consistent with the observed spin-down of the white dwarf and provides for much of the UV/optical emission by reverberation of X-rays. From previous X-ray and UV/optical data, we derive an accretion luminosity L_acc=(2.6±0.8)x10³⁴erg/s, a white dwarf mass M₁=0.93±0.12M_☉, and an accretion rate {dot}(M)=(1.4±0.3)x10¹⁷g/s.
