Fig. 10


Top: projection onto the Galactic plane of isolated Cepheids (black dots) and Cepheids members of candidate CGs (yellow dots). The ellipses mark the edges of individual CGs. They are also labeled with the identification number given in Table 6. The red dot shows the position of the Sun. The colored lines show a logarithmic model of the spiral arms (Vallée 2002; Cordes & Lazio 2002, see text for details). The names of the spiral arms are labeled. Bottom: running average of Cepheid metallicity residuals vs. Galactocentric radius (black line). The red dots mark the mean metallicity of the candidate CGs once the metallicity gradient has been subtracted. The red vertical lines display the intrinsic dispersion in iron of candidate CGs. The red horizontal lines show the inner and outer Galactocentric distance of individual candidate CGs (see Cols. 6 and 7 in Table 6).
