Detailed Description

Calculate pedestals for swic scanner channels using raw beam data.

This class maintains one UtilRunningAverageVector object for each SWIC scanner worth of channels.

Note:
There is no attempt to determine if a SWIC channel is bad! A pedestal will be happily calculated even if there are noisy channels.

Constructor & Destructor Documentation

BDSwicPeds::BDSwicPeds (   ) 
 

Create default BDSwicPeds. This will use BDDevices::SwicDevices() to form a ChannelsList

BDSwicPeds::BDSwicPeds (  const SwicMap &  map  ) 
 

Create a BDSwicPeds with pre-existing swic map. The map will be shallow copied. This transfers ownership of the URAV's.
