Field 36: Type of parallax

The following abbreviations are used: `T' for trigonometric, `D' for dynamical.

[]There are 5485 trigonometric parallaxes in the Input Catalogue, which were taken, via SIMBAD, from the General Catalogue of Trigonometric Parallaxes (Jenkins 1952) and its supplement (Jenkins 1963). There are also 389 dynamical parallaxes, taken from Dommanget (1967) and Dommanget & Nys (1982). Since the New General Catalogue of Trigonometric Parallaxes (van Altena et al., in preparation) was not available at the time of publication of the Input Catalogue, no more recent parallaxes are given here.
