 ### Description
 This module loads data from hdf5 files and adds it to the clipboard. The input file must have extension `.h5` without any compression filters and follow the structure below:
 
-| column |  row  | charge |       timestamp      | trigger_number |
+| column |  row  | charge |   timestamp \[ns\]   | trigger_number |

 ### Parameters
 * `filename`: Input file name.
 * `dataset_name`: Name of the node in the hdf5 file.
-* `buffer_size`: Buffer size for chunking.
-* `event_length`: Duration of the event if this module is the first event loader and defines the event. Ignored otherwise.
+* `buffer_depth`: Buffer size (entries) for chunking. Default is 100,000.
+* `event_length`: Duration of the event if this module is the first event loader and defines the event. Defaults to `1 us`.
 * `sync_by_trigger`: Add records to the clipboard based on its trigger instead of timestamp. This requires an event definition with trigger information and can therefore not be used as first event loader.
 * `timestamp_shift`: Shift the timestamp of the record by the defined value in nanoseconds.
 * `trigger_shift`: Shift the trigger of the record by the defined value.
