Notes. The column labelled Tcolour(V − K)0 has been used to draw the HR diagram of Fig. 1, EB − V is the reddening obtained from the SED fits presented in Figs. B.1−B.9.

(a)

HD 112127 is a carbon star; hence BCK from J − K and Eq. (1) of Kerschbaum et al. (2010).

(b)

This value of the colour temperature is obtained from the non-dereddened V − K index, as the dereddened index would yield instead an unrealistically high temperature of 5660 K.
