Notes. Objects in which the characteristic RV Tau features have been identified in the light curve are listed as RV Tau. Otherwise, if a pulsation period has been detected it is listed as “Puls.”, and if no period is known in the literature the source is denoted as “pAGB”. The (maximum) amplitude of pulsational variability in the V band is given, as well as the main pulsation period wherever relevant.

(a)

Peak-to-peak amplitude.

(b)

The main pulsation period.
