Re: [Brahms-dev-l] DCs

Hi Truls,
cc/ pawel

Thanks for reminding us.
-This was a failure in the tdc so there was not a failure or in-effeciency
in the trigger.
-Since the bottom workedd fine and the time differenc between top and bottom
is small
  it would be easy for those runs just to use the bottom time.
