K–log(P) diagram containing the variable stars identified in the LMC by Ita et al. (2004). Also shown are the P − K relations as fitted by the same authors. Both kinds of data were shifted to an absolute scale by assuming a distance modulus (m–M)_LMC of 18.5^mag. Overplotted are the C-type Miras adopted from Whitelock et al. (2006; cf. their Tables 3 and 6) as well as the sequence of dynamic model atmospheres presented in this work.
