ADC_Keywords: Stars, fundamental ; Combined data ; Positional data ; Radial velocities ; Proper motions ; Parallaxes, trigonometric ; Spectral types ; Cross identifications Description: The catalogue of radial velocities of Galactic stars with high precision astrometric data, 2nd version (CRVAD-2), is the result of a merging of star lists from the All-Sky Compiled Catalogue of 2.5 Million Stars (ASCC-2.5, Cat. I/280) with the General Catalogue of Radial Velocities (GCRV, Cat. III/213) and with other recently published radial velocity lists and catalogues. Cross identification of objects was carried out with help of coordinate, magnitude, colour and/or spectral type criteria. Data from the Catalogue of Components of Double and Multiple Stars (CCDM, Cat. I/274) were taken into account for the identification of multiple system components. Altogether 54907 stars from the ASCC-2.5 were identified with 51762 stars from the RV source catalogues, 3085 stars have secondary components and 30 stars have 3rd components in multiple systems. The CRVAD-2 includes accurate J2000 equatorial coordinates, proper motions and trigonometric parallaxes in the Hipparcos system, Johnson's BV photometric data, spectral types, radial velocities, multiplicity and variability flags. Stars are sorted in the order of increasing right ascension J2000. This catalogue supersedes the previous version numbered III/239. File Summary:

Note on v1: Byte 292 (T47=Var) from Tycho-1 file tyc_main.dat (I/239/tyc_main), as follows: G = variable known in the General Catalog of Variable Stars (Cat. II/250) N = variable known in the New Suspected Variables catalog (Cat. II/250) Note on v2: Byte 294 (T48=VarFlag) from Tycho-1 file tyc_main.dat (I/239/tyc_main), as follows: U = apparent variability in the Tycho data; may be due to duplicity V = strong evidence of intrinsic variability W = suspected intrinsic variability Note on v3: Byte 322 (H52=HvarType) from Hipparcos file hip_main.dat (I/239/hip_main). Hipparcos-defined type of variability (a blank entry signifies that the entry could not be classified as variable or constant): C = no variability detected ("constant") D = duplicity-induced variability M = possibly micro-variable (amplitude < 0.03mag) P = periodic variable R = V-I colour index was revised due to variability analysis U = unsolved variable which does not fall in the other categories Note on v4: Flag from CMC11 catalogue (I/256) as follows: V = variable star Y or I = if the CAMC did not measure the magnitude, an approximate value from other sources is given to a precision of 0.1mag X or R = star fainter than 12 with unknown mag is given as 12. Note on d12: Bytes 149-150 from Tycho-2 file catalog.dat (I/259/catalog). CCDM component identifiers for double or multiple Hipparcos stars contributing to this Tycho-2 entry. Note on d3: Byte 41 (DC7=comp_id) from Hipparcos file hipdmcom.dat (I/239/h_dm_com). Note on d4: Byte 296 (T49=MultFlag) from Tycho-1 file (I/239/tyc_main). Unresolved duplicity status from Tycho data analysis: D = duplicity clearly indicated (B_Tmag and V_Tmag 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 Note on d5: Byte 347 (H59=MultFlag) from Hipparcos file (I/239/hip_main). Indicates that further details are given in the Hipparcos Double and Multiple Systems Annex: C = solutions for the components G = acceleration or higher order terms O = orbital solutions V = variability-induced movers (apparent motion arises from variability) X = stochastic solution (probably astrometric binaries with short period) Note on SpType: was compiled from Spectral type given in the ASCC-2.5 (I/280) and GCRV (III/213) Note on IRVC: Index of Radial Velocity Catalogues from the following references: 1 = Famaey et al., 2005, Cat. J/A+A/430/165 2 = Gontcharov, 2006, Cat. III/252 3 = Nordstrom et al., 2004, Cat. V/117 4 = Barbier-Brossat & Figon, 2000, Cat. III/213 5 = averaged of Cat. III/213 and Cat. J/A+A/430/165 Note on Comp: Components from CCDM (I/274) copied from the GCRV (III/213) or letter "d" as an index of multiplicity from V/117. Note on q_RV: Quality flag as follows: A = standard error of 0.74km/s B = standard error of 1.78km/s C = standard error of 3.70km/s D = standard error of 7.40km/s E = standard error of 10.0km/s I = insufficient data
