Values for the coefficients of the PL, PW and PLC relations for BL Her and W Vir Cepheids taken from the literature. The PW functions are defined as in Table 5. The errors of ZP take into account the uncertainties in the transformation of the J and Ks photometry to the VISTA system (see the text for details).
