Description of Dataset:
The Hipparcos and Tycho Catalogues are the primary products of the European Space Agency's astrometric mission, Hipparcos. The satellite, which operated for four years, returned high quality scientific data from November 1989 to March 1993. Each of the catalogues contains a large quantity of very high quality astrometric and photometric data. In addition there are associated annexes featuring variability and double/multiple star data, and solar system astrometric and photometric measurements. In the case of the Hipparcos Catalogue, the principal parts are provided in both printed and machine-readable form (on CDROM). In the case of the Tycho Catalogue, results are provided in machine-readable form only (on CDROM). Although in general only the final reduced and calibrated astrometric and photometric data are provided, some auxiliary files containing results from intermediate stages of the data processing, of relevance for the more-specialised user, have also been retained for publication. (Some, but not all, data files are available from the Centre de Donnees astronomiques de Strasbourg.) The global data analysis tasks, proceeding from nearly 1000 Gbit of raw satellite data to the final catalogues, was a lengthy and complex process, and was undertaken by the NDAC and FAST Consortia, together responsible for the production of the Hipparcos Catalogue, and the Tycho Consortium, responsible for the production of the Tycho Catalogue. A fourth scientific consortium, the INCA Consortium, was responsible for the construction of the Hipparcos observing programme, compiling the best-available data for the selected stars before launch into the Hipparcos Input Catalogue. The production of the Hipparcos and Tycho Catalogues marks the formal end of the involvement in the mission by the European Space Agency and the four scientific consortia. For more complete and detailed information on the data, the user is advised to refer to Volume 1 ("Introduction and Guide to the Data", ESA SP-1200) of the printed Hipparcos and Tycho Catalogues. The user should also note that in order to convert the Double and Multiple Systems (Component solutions) data file hip_dm_c.dat into FITS format it is first necessary to filter the file according to whether the entry is a component record (identified by COMP in field DCM5) or a correlation record (identified by CORR in field DCM5) because of the different structures of the respective records. On a Unix system this can be achieved as follows: grep COMP hip_dm_c.dat > h_dm_com.dat grep CORR hip_dm_c.dat > h_dm_cor.dat The catalogue description file (this file) gives the relevant information for converting the main data files, including h_dm_cor.dat and h_dm_com.dat, into FITS format. The machine readable data files (i.e. those available on CD-ROM and the subset available from the CDS) contain several extra fields in addition to the data from the printed catalogue. These fields are identified by the letter `M' in the data label (e.g. the field DGM1 contains data only available in the machine readable file hip_dm_g.dat).Details:

(aq) this is the date when the photocentre is closest to the centre of mass in the orbital plane. It is equivalent to the closest approach of the stellar components. | |
(ar) this is the angle in the orbital plane from the line of nodes to the major axis, measured from the nodal point (DO8) to the periastron in the direction of motion. | |
(as) the inclination of the orbital plane to the tangent plane of the sky. Taken to be in the first quadrant if the apparent motion is direct (counter-clockwise) and in the second quadrant for retrograde (clockwise) apparent motion. | |
(at) This is the position angle (measured counter-clockwise as seen on the sky from the +Dec direction) of the line of nodes, or the intersection of the orbital and tangent planes. If the radial motion of the components is known from spectroscopic studies, then Omega should give the position angle of the ascending node, at which the primary star crosses the tangent plane while receding from the observer. In the absence of spectroscopic information Omega refers to the mode with the smallest positive position angle. | |

(ca) the designation of an object in the Tycho Catalogue uses the Guide Star Catalog numbering system (a region number (TYC1) and a number within the region (TYC2)) followed by a Tycho specific component number (TYC3). | |
(cb) ">if non blank, the field has the following meaning: B : no VTmag available, therefore BTmag was adopted D : derived from approximate BTmag and VTmag (r_BTmag field T36 is 'D') T : derived from approximate VTmag (r_BTmag field T36 is 'T') V : no BTmag available, therefore VTmag was adopted in Vmag | |
(cc) right ascension and declination are expressed in degrees for epoch J1991.25 (JD2448349.0625 (TT)) in the ICRS (International Celestial Reference System, close to J2000) reference system. | |
(cd) 'X' indicates a dubious astrometric reference star in the context of the Tycho catalogue. | |
(ce) For these fields the second decimal digit is always blank | |
(cf) values exceeding +2.5 to +3 indicate a bad fit to the data. | |
(cg) ">the source flag has the following meaning: D : approximate BTmag, VTmag obtained for resolved double stars M : BTmag and VTmag are median values rather than de-censored means N : BTmag and VTmag are de-censored means T : BTmag is not given, and VTmag is an estimate; these magnitudes are systematically too bright by up to 1mag. A blank indicates an Hipparcos star not observed by Tycho (T42 = H). | |
(ch)"> the astrometric quality flag is defined by the following table, where sigma(max) is the largest of the 5 astrometric standard errors: --------------------------------------------------------- Q sigma(max) Astrometric quality --------------------------------------------------------- 1 < 5 very high 2 5- 10 very high 3 10- 25 high 4 25- 50 high 5 50-150 medium 6 < 150 perhaps non-single 7 < 150 low 8 < 150 perhaps non-stellar 9 ~ 200 low, position derived from TICR ('R' in Source field T42) blank --- unassigned, 'H' in Source field T42 (Hipparcos star not observed by Tycho) | |
(ci)"> H : Hipparcos star not observed by Tycho P : only the position was determined (no proper motion, no parallax) R : the position is derived from TICR catalog <I/197> | |
(cj)"> this flag is set when the variability is known: G : variable known in General Catalog of Variable Stars <II/139> N : variable known in New Suspected Variables catalog <II/140> | |
(ck) ">this flag has the following meaning: U : apparent variability in the Tycho data; may be due to duplicity V : strong evidence of intrinsic variability W : suspected intrinsic variability | |
(cl)"> unresolved duplicity status from Tycho data analysis: D : duplicity clearly indicated (BTmag and VTmag refer to combined light) R : duplicity weakly indicated, combined with indication of variability S : duplicity suspected Y : investigation for duplicity carried out on Tycho data, no indication of duplicity was found Z : investigation for duplicity not carried out blank : Hipparcos star not observed by Tycho | |
(cm) from the 3 parts of the PPM catalogue North <I/146>, South <I/193>, and 90000Supplement <I/208> | |
(cn) ">if non-blank, the remark has the following meaning: J : disagreement with position of magnitude in GSC1.1 catalog <I/220> K : dubious Tycho parallax (Plx) L : dubious Tycho proper motion (disagrees with PPM catalogue) M : very uncertain Tycho magnitude (standard error larger than 0.3mag) |
