         to 65 by default. The default channels are the four operating conditions,

-
-         The default window size is, by default, the longest flight cycle in the
-         sub-dataset. Shorter cycles are padded on the left. The default padding value
-         is zero but can be overridden, e.g., as -1 to make filtering for padding easier
-         later on.
-
-         The default `run_split_dist` is the same as in the original dataset, but with
-         the last unit of the original train split designated for validation.
-
-         If the features are downsampled in time, the default window size is
-         automatically adjusted to `window_size // resolution_seconds`. Any manually
-         set `window_size` needs to take this into account as it is applied after
-         downsampling.
