Fit values of the peak position of the second wave in nine Italian regions and date when $R_t$ curve crosses the $R_t=1$ value, according to the Covidstat and the Cori algorithms, obtained with a straight line fit to the five $R_t$ values around $R_t$ =1

The difference of times $\mathrm{\Delta }t$ between the peak of the new cases and the day when $R_t=1$ are also reported. Days are counted since February $24\mathrm{th}$, 2020, day 260 corresponds to November $9\mathrm{th}$, 2020
