Topic: General Catalogue of Trigonometric Parallaxes

	CNS3 - Gliese Catalog of Nearby Stars, 3rd Edition
		The catalogue contains every then-known star with a trigonometric parallax greater than or equal to 0.0390 arcsec, even though it may be evident from photometry or for other reasons that the star has a larger distance.
		Generally, the preferred designations are GL, e.g., GL 10, the Gliese number, or the designation given to the star in the 2nd version of the Gliese Catalog (Gliese 1969), or GJ, e.g., GJ 1001, also often called the Gliese number, and derived from a tabulation of Gliese and Jahreiss (1979, Astr.

	WOOLLEY - Woolley Catalog of Stars within 25 Parsecs
		The parallaxes are trigonometric parallaxes in many cases, mostly taken from the "General Catalog of Trigonometric Stellar Parallaxes" and its supplement (Jenkins, L.F. 1952 and 1963, New Haven, Yale University Observatory).
		The probable error in the parallax of the star, in milliarcseconds (mas), for stars for which trigonometric parallaxes are available.
		This parameter has possible (non-blank) values of 8, 9, or S. A value of 8 means that the the percentage error in the (trigonometric) parallax is less than 15%, 9 means that it is < 10%, while a value of S means that the parallax quoted is a spectroscopic not a trigonometric parallax.

		Ptolemys catalogue was based to some extent on an earlier one by Hipparchus from the 2nd century B.C. An even earlier star catalogue was that of Timocharis of Alexandria, which was written about 300 B.C. and later used by Hipparchus.
		The catalogue was compiled by Annie Jump Cannon and her co-workers at Harvard College Observatory under the supervision of Edward Pickering, and was named in honour of Henry Draper, whose widow donated the money required to finance it.
		HIP The Hipparcos catalogue was compiled from the data gathered by the European Space Agency's astrometric satellite Hipparcos, which was operational from 1989 to 1993.

	Distance to Hyades Cluster
		The ground-based trigonometric parallaxes listed in the new edition of the Yale Parallax Catalogue (YPC; van Altena, Lee, and Hoffleit 1995) were recently analyzed by van Altena, Lee, and Hoffleit (1997), who found a distance of 46 pc.
		According to equation (1), after scaling due to differing angular distances from the convergent point, the distance of a star relative to the cluster center is given by the ratio of the star's proper motion to that of the cluster center.
		The HST parallaxes yield a cluster center distance (4.83 ± 2.0 pc) in agreement with the orbital parallaxes and the YPC for the Gunn et al.

		Following the coordinates, proper motions are given along with the weighted average absolute parallaxes, parallax error, number of parallax observations and a quality code.
		Volume II contains for each star, all published parallaxes, associated errors and sources of publication, the average magnitude of the reference frame, galactic coordinates, the correction to absolute parallax based on an improved model of the Galaxy, absolute parallax and its error and the weight of the parallax.
		The weighted mean parallaxes of many stars will be found to differ from those in the preliminary version due to changes in the weighting system, revisions to the default reference star magnitudes and the addition of new data.

		The fourth edition of "The General Catalogue of Trigonometric Stellar Parallaxes," recently published by the Yale University Observatory, is not exactly the type of light reading most people would take to the beach.
		That was the year astronomer Frank Schlesinger published the first parallax catalogue in which opposite points on the earth's annual orbit around the sun were used for measuring star distances.
		However, stars in the parallax catalogue can be used as yardsticks to gauge distances to stars at the fringes of the universe, based on their relative brightness compared to parallax stars, explains Professor van Altena.

		Statistical parallaxes estimate the mean parallax of groups of stars, assuming that their proper motions are random, by comparing their radial velocities with their proper motions.
		Secular parallaxes are found, again as the means for groups of stars, but using the baseline created by the sun's spatial motion (2.8 AU per year).
		Dynamical parallaxes are found for binary stars where the orbital semimajor axis in arc-seconds (a), the orbital period in years (T), and the masses of the two stars in solar masses (m1, m2) is known.

		In general, due to the high proper motion of many of these catalogued stars, the 1950 co-ordinates when precessed to the 2000 equator will be slightly different than RA_J2000 and Dec_J2000, since the former do not include a correction for the (50 years of) proper motion.

	FK4SUP
		This catalogue lists improved mean positions and proper motions for the 995 stars in the FK4 Supplement (FK4S, Fricke 1963) which were not included in the FK5 (Fricke et al.
		The main purpose of the FK4S was to stimulate further observations within absolute and differential programs of the stars listed in that catalogue with the aim of their inclusion as new fundamental stars into a future fundamental catalogue.
		Although the astrometric precision of the stars given in the present catalogue is inferior to that of the FK4S stars included in the FK5E, they deserve being published because a considerable number of observations has been obtained for these stars since about 1955, stimulated by the publication of the FK3S.

	The Distance to a Stellar Youngster by Ken Croswell
		Unlike the Sun and other main-sequence stars, which generate light by converting hydrogen into helium at their cores, T Tauri stars shine by tapping the force of gravity.
		The larger the shift, or parallax, the closer the star is to Earth.
		And the star's negative parallax in the 1995 edition of The General Catalogue of Trigonometric Stellar Parallaxes is useless.

		In the Introduction to the printed Catalogue, an analysis of the resulting absolute parallaxes has been made to study the accidental and systematic errors of the parallaxes.
		The weighted mean parallaxes of many stars will be found to differ from those in the preliminary version due to changes in the weighting system, revisions to the default reference star magnitudes and the addition of new parallaxes.

		Existing calibrations of white dwarf luminosities have invariably relied upon the inhomogeneous sample of refractor parallaxes published in the General Catalogue of Trigonometric Stellar Parallaxes.
		The properties of the stars in this sample are well enough established that statistical luminosity corrections resulting from the combination of parallax errors with the space distribution peculiar to the stars can be established fairly reliably.
		The resulting luminosity calibration is in very good agreement with previously published results, and is of sufficient accuracy to investigate for the subset of DA-type stars the expected dependence on surface gravity (or mass) predicted theoretically from the white dwarf mass-radius relation.

		Renowned for the quality of her data on the brightest stars and for observations of stars with variable brightness, she received the 1988 Van Biesbroeck Award for her unselfish dedication to astronomy and for publishing "The Bright Star Catalogue" in 1982, which documents 9,110 stars that are visible to the naked eye.
		Hoffleit and Yale colleagues William F. van Altena and John T. Lee finished an 18-year project by publishing the fourth edition of "The General Catalogue of Trigonometric Stellar Parallaxes." Astrophysicists worldwide depend upon its precise measurements of distances to 8,112 stars to explore questions about stellar evolution and the size and age of the universe.
		Hoffleit began her career as a research assistant and astronomer at Harvard College observatory 1929-56; during this period, she had a five-year World War II assignment as a mathematician at the Ballistic Research Laboratories, Aberdeen Proving Ground, Maryland.

	The Parallax Project
		Despite early experiments with photography, the precision of the measurements of stellar parallax did not improve much until the experiments of Frank Schlesinger with the Yerkes refractor between 1903 and 1905.
		Digital Research Library noted the parallax and radial velocity data contained in the 10-volume set.
		The parallax database records the same information for each star: star name, Allegheny Observatory number, BD number, right ascension hours, minutes, and seconds, declination degrees, minutes and seconds (like the Yale Catalogue, these are for the equinox of 1900), Henry Draper number, relative parallax, and parallax error.
