Local Kinematics of K and M Giants from CORAVEL/Hipparcos/Tycho-2 Data Famaey B., Jorissen A., Luri X., Mayor M., Udry S., Dejonghe H., Turon C. =2004A&A...???...??F Paper 1272 Keywords: Galaxy: kinematics and dynamics -- disk -- solar neighbourhood -- evolution -- structure -- stars: kinematics -- late-type Description: The table provides Hipparcos positions, Hipparcos & Tycho-2 proper motions, and CORAVEL radial velocities for 6691 K and M giants in the solar neighbourhood, mostly from the Hipparcos survey. A bayesian maximum-likelihood approach has been used to derive the distances and space velocities. New V-I indices, computed from a color transformation based on Hp - V_T2, are also provided. Spectroscopic binaries have been identified as well. These data may be used to study the kinematics of giant stars in the solar neighbourhood, and to correlate it with their location in the Hertzsprung-Russell diagram. ----------------------------------------------------------------------------------- Byte-by-byte Description of file: tableA1.dat ----------------------------------------------------------------------------------- Bytes Format Units Label Explanations 1- 6 I6 -- HIP HIP number 8- 13 I6 -- HD HD number 15- 17 I3 -- BDd First part of BD number (only when HD is missing) 20- 23 I4 -- BDn Second part of BD number (only when HD is missing) 26- 37 F12.8 deg RAd Right ascension J2000 (ICRS), Epoch 1991.25 (degrees), identical to field H8 of the Hipparcos Catalogue 39- 50 F12.8 deg DEd Declination J2000 (ICRS), Epoch 1991.25 (degrees), identical to field H9 of the Hipparcos Catalogue 53- 59 F7.2 mas varpi Hipparcos parallax (milliarcseconds) 61- 65 F5.2 mas evar Standard error on varpi (milliarcseconds) 69- 74 F6.1 mas/y MuA*T2 * Tycho-2 proper motion in right ascension, times cos(RA) (milliarcsec/y) 76- 79 F4.1 mas/y eMuAT * Standard error on MuA*T2 (milliarcsec/y) 83- 88 F6.1 mas/y MuDT2 * Tycho-2 proper motion in declination (milliarcsec/y) 90- 93 F4.1 mas/y eMuDT * Standard error on MuDT2 (milliarcsec/y) 96-102 F7.2 mas/y MuA*H Hipparcos proper motion in right ascension, times cos(RA) (milliarcsec/y) 104-108 F5.2 mas/y eMuAH Standard error on MuA*H (milliarcsec/y) 110-117 F8.2 mas/y MuDH Hipparcos proper motion in declination (milliarcsec/y) 119-123 F5.2 mas/y eMuDH Standard error on MuDH (milliarcsec/y) 125-131 F7.2 - MuH-T2 * Absolute difference between the Hipparcos and Tycho-2 proper motion moduli, normalized by the rms of their standard errors 133-139 F7.4 mag Hp Hipparcos Hp magnitude 141-146 F6.4 mag eps_Hp Standard error on Hp 148-153 F6.3 mag V_T2 Tycho-2 V magnitude 155-160 F6.3 mag Hp-VT * Difference Hp-V_T2. 162-166 F5.2 mag VIH40 V-I colour index as provided in field H40 of the Hipparcos catalogue 168-172 F5.2 mag V-I V-I colour index, computed from Hp-VT with the colour transformation of Platais et al.

An asterisk in this column indicates the presence of a note in the file table1.notes ----------------------------------------------------------------------------------- Note on MuA*T2: For 291 stars, null values in this and the following three columns indicates that the Tycho-2 is not available or has not been used in the analysis Note on MuH-T2: Values larger than about 2 hint at the possible binary nature of the star Note on Hp-VT: For visual binaries (flag = 4 in column B), this colour index has not been listed and a null value is given instead, because the Hp magnitude appears to be a composite value for the two visual components. For large amplitude variable stars, Hp-VT is meaningless as well, and a null value has been listed. ----------------------------------------------------------------------------------- ----------------------------------------------------------------------------------- Byte-by-byte Description of file: tableA1.notes ----------------------------------------------------------------------------------- Bytes Format Units Label Explanations 1- 6 I6 -- HIP HIP number 8- 80 A73 -- Note A note ----------------------------------------------------------------------------------- Author's address: Alain Jorissen (End) Alain Jorissen [Univ.
