P-L diagram for Miras of known spectral type in the sample. See the legend for the different spectral types, the number of stars in each Group, and the linear fit to each of them. The thick black line indicates the relation obtained by Sanders (2023) for Galactic Miras. The luminous M(B)-type Miras at log P ∼ 2.6 could be hot bottom burning candidates.
