cds-question@unistra.frvisible-astronomynarrow-band-photometrytwo-color-diagramslate-type-starsA cyanogen index for late-type giants, insensitive to surface gravity but sensitive to metallicity, is presented in the David Dunlap Observatory (DDO) photometric system. Observations were made using conventional single-channel photometers with 1P21 photomultiplier tubes on the 40cm and 90cm telescopes of Kitt Peak National Observatory. The original DDO filter set C was used (see Paper I, 1968AJ.....73..313M). Table 1 contains DDO photometry on 52 bright late-type giants for calibration. Most G8 to M0 stars, luminosity class III, V<4.0mag, north of {delta}=-10{deg}, supplement the original stars from Paper I. Table 4 includes both DDO and UBV photometry for stars from Schmitt (1967 thesis, Univ. Michigan, Ann Arbor) and Spinrad and Taylor (1967AJ.....72S.320S). Reddening values were computed using the method of McClure and Racine (1969AJ.....74.1000M).1970AJ.....75...41Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/II/46CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/45 : Photometry of strong CN stars (Janes+ 1971)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=II/46https://vizier.iucaa.in/viz-bin/VizieR-2?-source=II/46http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=II/46https://vizier.cds.unistra.fr/viz-bin/votable?-source=II/46https://vizier.iucaa.in/viz-bin/votable?-source=II/46http://vizieridia.saao.ac.za/viz-bin/votable?-source=II/46GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table II/46/table4 (Table 4: Strong-cyanogen stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/II/46/table4?https://vizier.iucaa.in/viz-bin/conesearch/II/46/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/II/46/table4?GETtext/xml+votable180.050000true7.400544262.06415140.005555555555555556Cone search capability for table II/46/table1 (Table 1: Bright calibration stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/II/46/table1?https://vizier.iucaa.in/viz-bin/conesearch/II/46/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/II/46/table1?GETtext/xml+votable180.050000true4.8569756-8.82391970.0055555555555555566/1246 1249 1297 1299 1380 1420 1505 1877 1885 1967 1979 1998 2282 2549 2834 2837 2973 3023 3057 3197 3252 3253 3331 3634 3654 3658 3777 4146 4444 4574 4702 4711 4783 4804 5245 5535 5587 5744 5750 5938 5945 5984 5998 6007 6067 6126 6166 6203 6298 6740 7008 7094 7103 7262 7263 7290 7339 7365 7375 7402 7434 7545 8348 9083 9127 9213 9219 9610 10101 10738 10742 10788 10800 10886 10917 11007 11071 11094 11167 11181 11192 11378 11383 11412 11436 11447 11453 11473 12082 13158 13333 13778 13882 14199 14302 14371 14431 14535 14632 14635 14800 14963 15185 15226 15303 15363 15429 15469 15629 15667 15686 15715 16023 16150 16213 17266 17487 17551 17608 18416 18710 18911 18944 20311 21457 21612 22450 23643 23644 23655 24358 24424 25246 25910 26552 26758 28149 28173 28487 28523 28529 28613 29533 29589 29788 29800 30037 30100 30343 30438 30452 30455 30518 30643 30665 30681 30953 31475 31488 31760 31808 31814 31987 32089 32093 32182 32225 32303 32502 32609 32754 36759 40795 44518 45050 488863.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/II/46?format=asciiOpticaldefaultII/46/table4Table 4: Strong-cyanogen starsrecnoRecord number assigned by the VizieR team.
