A census of AGB stars in Local Group galaxies. II. NGC 185 and NGC 147. Nowotny W., Kerschbaum F., Olofsson H., Schwarz H.E. <Astron. Astrophys. 403, 93 (2003)> =2003A&A...403...93N
ADC_Keywords: Galaxies, photometry ; Stars, giant ; Stars, carbon Keywords: stars: AGB and post-AGB - stars: carbon - galaxies: Local Group - galaxies: individual: NGC 185, NGC 147 - surveys surveys Description: The tables represent results of an ongoing photometric survey of Local Group galaxies, using a four filter technique based on the method of Wing (1971, Proc. of the Conference on Late-Type Stars, ed. G.W. Lockwood and H.M. Dyck, KPNO Contribution 554, 145) to identify and characterise the late-type stellar content. Two narrow band filters centred on spectral features of TiO and CN allow us to distinguish between AGB stars of different chemistries [M-type (O-rich) and C-type (C-rich)]. The major parts of two dwarf galaxies, NGC 185 and NGC 147, were observed; 154 new AGB carbon stars in NGC 185 and 146 in NGC 147 were identified. All detected stars (called sample 1 in the paper) are included in the tables, with coordinates and photometric properties. All stars of sample 1 have photometry in the filters V and i. For all stars, which are in addition included in the smaller sample 2 (and have also photometry in the narrowband filters TiO and CN) the colour index (TiO-CN) is provided, too. In the tables a chemistry flag F marks in which classification group the star falls. All stars of sample 2 can have "c" for Carbon star, "o" for oxygen-rich M-type star or "r" for the rest. This correspond to the selection areas in Figure 4 of the paper. The flag for all stars of sample 1, which are not already included in sample 2 (only Vi-photometry) is "u" for unclassified.
