Appendix A

This appendix presents the spectra of C stars listed in Table 1 of the paper (eight halo C stars, four FBS halo stars, three C stars in Carina, and eight Fornax C stars). The CN and C₂ bands dominate these spectra, occasionally with Hα in emission (indicated). The strong absorption feature at 7600 Å  is due to telluric O₂. The scaling factors f to obtain the ordinates in erg s^-1 cm^-2 Å^-1 is given in Table A.1. The FBS stars have no flux calibration. Note that almost all these stars are subject to variability.

Table A.2 presents the list of objects in the field of Fornax for which EFOSC2 spectroscopy was analysed and which are not C stars. These stars are mostly M-type foreground dwarfs, except for the object 2MASS J024000.78−341812.2, which appears fuzzy along the slit in the spectra and is probably a galaxy.

In Table A.4, the periodic variables found with Catalina and LINEAR data are listed. In the first column, the objects named “SDSS Green #nnn” are taken from Table 1 of Green (2013), where nnn is the object rank in his table. Similarly, the object named 2MASS Gizis #32 comes from Table 1 of Gizis (2002). The names “mxxx” come from the lists in Paper I to IV.
