Difference between"RepetitionTime" and "RepetitionTimeExcitation"

Hi all,

I have some .json files related to functional scans that contain the keys: “RepetitionTime”: 6.02353, “RepetitionTimeExcitation”: 3.001. I have read in some previous threads that RepetitionTime = RepetitionTimeExcitation + RepetitionTimePreparation for anatomical scans - can I assume that here too? And can I assume that my TR for these cases is RepetitionTimeExcitation?
