+    Cleaning is part of the harmonic analysis in `harpy` as the [frequency analysis is done on the v-matrix of the SVD][harpy_analysis]:
     SVD is used to reduce the noise in the BPM data by selecting only the most important modes and in the same step also to detect bad bpms.
     As this decomposition is a linear transformation, the frequency analysis can be run directly on decomposed v-matrix, without
     having to re-compose the data into the time-domain, saving time and memory.
     The disadvantage is that, as we do not save the SVD matrices, there is no way to only run _cleaning_ without frequency analysis at the moment.
