+ | The way to avoid this is is to calculate the total correlation. This is not a start-stop correlation but the correlation of every photon against every photon. | ||

+ | |||
+ | For a trial you will I need the raw data - a pt2 file containing all the photon data - not just the correlated curve. You can record this using the button I highlighted in the attached screenshot. | ||
