That looks like the inner layer only.  It is the 5x5 box around the 3x3 hole.

It sounds like PrimEx recommendation would be to enlarge to include the next 7x7 square outside of that.

Hi all,

A quick follow-up to the discussion today, here is a code snippet that indicates the fiducial cut around the beamhole - basically, showers whose centers are in these blocks are rejected for analysis.

 // build list of channels in the inner ring.  Pick all channels which
 // touch the beam hole (including corners!)
 dFCALInnerChannels.push_back( dFCALGeometry->channel( 27, 27 ) );
 dFCALInnerChannels.push_back( dFCALGeometry->channel( 27, 28 ) );
 dFCALInnerChannels.push_back( dFCALGeometry->channel( 27, 29 ) );
 dFCALInnerChannels.push_back( dFCALGeometry->channel( 27, 30 ) );
 dFCALInnerChannels.push_back( dFCALGeometry->channel( 27, 31 ) );
 dFCALInnerChannels.push_back( dFCALGeometry->channel( 31, 27 ) );
