Notes. The PL relations have the form y = α + β × x, where x, and y are the period and magnitude, respectively. For PLCs we have z = α + β × x + γ × y, where x, y, and z are the period, colour and magnitude, respectively. Additional fits are in the Appendix C.2 (Table C.1). The different columns report: (1) the type of relationship and the band of interest; (2) the pulsating class; (3) and (4) the α coefficient (intercept) and relative uncertainty; (5) and (6) the β coefficient (slope as a function of the period) and relative uncertainty; (7) and (8) the γ coefficient (colour term of the PLC) and relative uncertainty; (9) the Root Mean Square (RMS) of the relation; (10) and (11) the number of stars used in the fit and the total number of stars, respectively.
