Derived LF distribution of the present study (blue histogram, excluding J- and R-hot-type stars), compared to those obtained by Gullieuszik et al. (2012) (black dotted line) in the VMC survey of carbon stars, Guandalini & Cristallo (2013) (red dotted line) in Galactic AGB carbon stars, and Whitelock et al. (2006) in Galactic Mira carbon stars (green dashed line). The LFs of these studies have been re-binned with a 0.25 mag step for better comparison.
