.. py:function:: return_llnl_catalog_origin_times(event=None)

   Returns a static LLNL catalog which provides origin times and event tags

   :type event: str
   :param event: returns only a specific event based on the event names
   :rtype: dict
   :return: a dictionary where keys are event names (uppercase) and values
       are catalog origin times (UTCDateTime)


.. py:function:: scale_llnl_waveform_amplitudes(st)

   Rescale amplitudes for LLNL data. The scales are different for different
   channels.

   .. note::
       Old factors
       BB = 4.0e-4
       HF = 1.8e-2
       HF = 1.8e-4

   .. note::
       scales based on tests with events HOYA, BEXAR
       * LL.HOYA..LH? and LL.HOYA..BB? require a sign flip. Otherwise the
           surface waveform inversions produce a -ISO result.
       * LL.HOYA..LH? and LL.HOYA..BB? body do not require flip.

   :type st: obspy.core.stream.Stream
   :param st: Stream containing LLNL waveforms
   :rtype: obspy.core.stream.Stream
   :return: Stream with scaled LLNL waveforms
