Raw and Meta-data for coherence measurements with trapped Ca-ions

The data is the outcome of several scans over the phase of a ramsey-interferometer in an experimental 40Ca+ ion trapping apparatus. It was used to perform contrast scans in order to retrieve the coherence time of different interrogation schemes. The datasets scan-parameter, scan-excitation scan-parity can be directly used to access the evaluated measurement data, also all other meta-data of the experiment is present.
