The file labeled "467_flop_01.txt" contains data for the spectroscopic interrogation of a single Yb+ ion using light at 467nm to excite the octupole transition. Within the measurement the pulse length of the excitation beam was scanned while the frequency was kept constant.

The columns of the files show the UTC time in seconds, the time passed since the start of the experiment in seconds, the pulse time of the excitation pulse in microSeconds, the probability of detecting a non-excited ion in a given region of interest of the camera image, the number of valid experiments. The last column is irrelevant for the measurement.

The data was used to determine the shortest possible excitation time of the 467nm octupole transition in our experiment (Fig. 2b of the manuscript).
