Notes.
For all the stars, either the stellar diameter (θd) or Teff (or both) are derived from direct measurement; there are no objects for which indirect calculations are used for both parameters. The references in the footnotes refer to the direct measurements. The other parameter is then derived from the relation L(R⋆, Teff) with R⋆ determined from the stellar diameter and the distance.
Derived from the Mbol(P, L) relation in De Beck et al. (2010) unless indicated otherwise.
Estimate of the local standard of rest velocity derived from a sample of rotational lines with well behaved line profile shapes and laboratory measured frequencies observed in the ALMA ATOMIUM survey.
Mira variables have regular, large amplitude variations in the visible with δV > 2.5 mag and are thought to be fundamental mode pulsators; semiregular variables (SR) are of smaller amplitude, δV < 2.5 mag, with pulsations in the fundamental, first, and even higher overtone modes (Wood 2015). Semiregular variables that have stable periodicity are classified as SRa, while variables with different duration of individual cycles are classified as SRb. SRc semiregulars are variable supergiants. A source is classified as a long-period variable (LPV) if no regular pulsation period P could be deduced from the observations, in which case P is indicated by ‘⋯’ in Col. 4.
