Notes. Numbers in Cols. 2 and 3 correspond to the samples before and after the validation and cleaning described in Sect. 6, respectively. Numbers in Col. 4 are after adding the 14 RR Lyrae stars discussed in Sect. 6.6.

(a)

“New” means “new to the best of our knowledge”.

(b)

Regions for the LMC, SMC, and all-sky are as defined in Sect. 2.

(c)

Numbers of RRab and RRc stars in column Nclean(−14) are corrected for the reclassifications in Sect. 6.1.

(d)

Numbers of RR Lyrae and Cepheids with RV time-series data published in DR3 are corrected in column Nclean(−14) for the reclassifications in Sects. 6.5 and 6.9.
