For reference, this is how we decimate fronts now:

Values are top decimated energy level/decimation depth
      
               ____________Shutters____________
SSR level     open     thin      thick     both
                                (unused)
50-60          6/1      7/1        8/1     9/1 
60-70          6/2      7/2        8/2     9/2 
70-80          8/3      9/3       10/3    11/3 
80-90         10/5     11/5       12/5    13/5 
90-95         12/7     13/7       14/7    15/7 
95-98         14/8     15/8       15/8    15/8 
98-99         15/15    15/15      15/15   15/15    
99+ events off.

Decimation depth N means N out of (N+1) events are deleted.
The top decimation energy levels are APPROXIMATELY:

  Energy     Top       Top
  Level     Channel   Energy
                      (keV)
       0      15      [<0, no decimation]
       1      31      [<0, no decimation]
       2      47      2.98000
       3      63      8.42000
       4      79      13.8600
       5      95      19.3000
       6     111      24.7400
       7     127      30.1800
       8     143      35.6200
       9     159      41.0600
      10     175      46.5000
      11     191      51.9400
      12     207      57.3800
      13     223      62.8200
      14     239      68.2600
      15     255      73.7000

Note we never decimate using an energy threshold below 25 keV.
