# The following line is called automatically when setting the PSDs, which we donnot do here hence the line.
# Stangely however, in bilby, the `Interferometer` class does not have `duration` and `sampling_frequency` arguments when the `InterferometerStrainData` and the `InterferometerList` classes do. Hence one needs to set those arguments for the list of `InterferometerStrainData` so that the `InterferometerList` inherits from them. The values will be inherited from the first one in the list...
