  1. See text for details regarding the methods. All estimates were obtained using the first 32 days of data (default column) or the best fitting time window (“optimal” column). For the SB method, the optimal reported estimate was obtained on day 22, as this date best fits the end of the exponential growth period. For the TD method, daily estimates were averaged over the 32 first days.
