      or "koopman", which uses the re-weighting procedure from [1] to compute equi-
      librium covariance matrices. The user can also supply his own re-weighting me-
      thod. This must be an object that possesses a function weights(X), that assigns
-     a weight to every time-step in a trajectory X.
+     a weight to every time-step in a trajectory X. #1007
    - covariance_lagged: This new method can be used to compute covariance matrices
      and time-lagged covariance matrices between time-series. It is also possible
      to use the re-weighting method from [1] to compute covariance matrices in equi-
      librium. This can be triggered by the option "weights", which has the same spe-

    - estimate_markov_model: New option "weights". Can be empirical, which does the
      same as before, or "oom", which triggers a transition matrix estimator based
      on OOM theory to compute an equilibrium transition matrix from possibly non-
-     equilibrium data. See Ref. [2] for details.
