Basic properties of RRd stars derived from the analysis of the OGLE-IV photometry. Period of the dominant mode is written with bold font. Asterisk at mode amplitude indicates that unresolved signal remains at f₀ or at f₁ in the frequency spectrum of the data pre-whitened with the full light-curve solution.
