All Tables

Table 1: Carbon stars observations log and properties.
Table 2: Spectroscopic parameters of the new identified lines.
Table 3: Main characteristics of the extragalactic C-stars. We give the stellar name, the effective temperature, the mean metallicity [M/H], the carbon over oxygen abundances ratio (C/O), the corresponding difference between carbon and oxygen abundances ( $\epsilon \rm (C)-\epsilon (O)$ ), the carbon isotopic ratio and the range of estimated bolometric absolute magnitudes.
Table 4: Summary of the abundances derived in the programme stars. N, indicates the number of lines utilized for a specific element if more than one line was used (we then give the mean abundance together with its dispersion). [el/M] is the abundance ratio with respect to the mean derived [M/H] (see text and Table 3) and is only quoted for elements with $A\geq 30$ .
Table 5: Metallicity and the s-process indices of the extragalactic C-stars studied. The typical error in $\rm {[M/H]}$ and $\rm {[hs/ls]}$ is $\pm$ 0.3 dex and the average error on the other indices is $\pm$ 0.35 dex.
