Beginning of ReadMe : II/46 Strong cyanogen stars (McClure 1970) ================================================================================ A Photometric Investigation of the Strong Cyanogen Stars, Table 1: Bright Calibration Stars; Table 4: Strong Cyanogen Stars McClure R.D. <Astron. J., 75, 41 (1970)> =1970AJ.....75...41M ================================================================================ ADC_Keywords: Photometry, CN band; Colors; Stars, cyanogen Description: A 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=-10deg, 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).
