Notes. First part shows the parameters determined after application of the model functions of LMC₁ in Equation (1) to the CSS and ZTF light curves. The second and the third parts show the parameters determined after application of the model functions of LMC₂ in Equation (5) and of LMC_ph in Equation (4) to the CSS and ZTF light curves. The parameters of T_QPO and $T_{{QPO}_{1}}$ $T_{{\mathrm {QPO}}_1}$ are the periodicities in units of days.
