K − [22] vs. P diagram of the 27 stars in Table 1; see the legend for the identification of the three types of period change. The red solid line is the relation that best separates Tc-poor from Tc-rich Miras following Eq. (1). The arrows attached to the symbols of the SPC stars indicate their recent period evolution.
