Estimates and standard errors (SE) of the thermal inactivation parameters obtained from the data retrieved for spores of Clostridium perfringens, Salmonella Senftenberg, Enterococcus faecalis and parvoviruses used in the simulations. Correlation values between estimates and standard deviations (SD) of residuals are also shown
