cds-question@unistra.frcarbon-starsradial-velocitystellar-distanceOptical radial velocities have been measured for 38 C-type Mira variables (C-Miras). These data together with others in the literature are used to study the differences between optical and CO millimetre (mm) observations for C-Miras and the necessary corrections to the optical velocities are derived in order to obtain the true radial velocities of the variables. The difference between absorption and emission-line velocities is also examined. A particularly large difference (+30km/s) is found in the case of the H{alpha} line. A catalogue is given of 177 C-Miras with estimated distances and radial velocities. The distances are based on bolometric magnitudes derived in Paper I (Whitelock et al., 2006, Cat. <J/MNRAS/369/751>) using South African Astronomical Observatory (SAAO) observations or (for 60 of the stars) using non-SAAO photometry. In the latter case, the necessary transformations to the SAAO system are derived. These data will be used in Paper III (Feast et al., 2006MNRAS.369..791F) to study the kinematics of the C-Miras.2006MNRAS.369..783Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/369/783CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/369/751 : Near-infrared photometry of carbon stars (Whitelock+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/369/783https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/369/783http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/369/783https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/369/783https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/369/783http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/369/783GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/369/783/table2 (New heliocentric radial velocities)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/369/783/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/369/783/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/369/783/table2?GETtext/xml+votable180.050000true67.844583317.65333330.005555555555555556Cone search capability for table J/MNRAS/369/783/table4 (Distance and velocity data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/369/783/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/369/783/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/369/783/table4?GETtext/xml+votable180.050000true34.527528.61341670.0055555555555555566/765 1297 1306 1371 1634 1647 1716 1727 1844 2910 2920 3026 3090 3192 3255 3287 3597 3766 3856 4365 5273 6407 6885 9262 9783 10103 12982 13113 13187 13677 13968 14048 14072 14212 14314 14325 14391 14425 14455 14458 14575 14600 14641 14738 14809 15384 15401 15415 15429 15554 15641 16144 16233 19112 19629 20022 20615 20824 21224 21338 21504 21515 21538 21560 21656 21912 22069 22093 22225 22235 22239 22241 22448 22507 23548 23606 23629 23640 23733 23808 23871 23971 24384 24501 24572 25486 26319 28796 28880 28891 29064 29214 29222 29443 29531 29545 29558 29855 30215 30265 30521 30603 30777 32062 32189 32331 36369 36986 37139 37210 37245 37334-37335 37341 37347 37366 37400 37405 37719 37751-37752 37759 37833 37863 37892 37894 37901 37908 37911 37913 37928 37930-37931 37936 37953 38018 38042 38862 39276 39323 39342 39387 39396 39416-39417 39766 39773 39888 39911 40066 40094 40150 40157 40168 40480 40492 40601 40617 40673 41530 41571 41580 41583 41676 41683 41692 41711 41738 41781 41786 41849 41872 41937 41945 42018 42218 42332 42351 42469 42516 42845 43040 43046 43055 43060 43066 43581 48869https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/369/783?format=asciiOpticaldefaultJ/MNRAS/369/783/table2New heliocentric radial velocitiesrecnoRecord number assigned by the VizieR team.
