The data files contain the data of Fig. 5(c) and (d).
	Fig. 5(c): CPMG_before.mat, CMPG_after.mat
	Fig. 5(d): Ramsey_off.mat, Ramsey_on.mat, Ramsey_on_nolinetrigger.mat

The keys of the data are the following:
	exc: single-ion excitation
	exc_mean: average of exc over the ions
	idstr: data and time of the measurement
	x: scan variable, length of Doppler cooling in microseconds (used to shift timing of experiment over line cycle)
