  1. All factors are stated so that an uncorrected measured activation rate has to be multiplied with these to obtain the activation rate in a very small sample
  2. TCC stands for true coincidence summing, ZDT denotes zero-dead time counting
  3. Unity values indicate that the participant deemed the correction negligible, blank values that no data were provided by the participant
