    keyword=Dithering parameters modified

    
    
    I modified the dithering parameters to try to make the most of the dithering 
    cycles.  First, the ticks per step from 18->24, which should provide more data 
    in each dither cycle (though fewer total cycles, and possibly more cycles 
    corrupted by beam trips or such).
    
    I modified the amplitudes as well:
    
    getConfigBMW()
    bmwCient::: listing Coils, number of cycles, and amplitude...
     coil: 0  Number of cycles: 1   Amplitude = 150 
     coil: 1  Number of cycles: 1   Amplitude = 150 
     coil: 2  Number of cycles: 1   Amplitude = 150 
     coil: 3  Number of cycles: 1   Amplitude = 450 
     coil: 4  Number of cycles: 1   Amplitude = 450 
     coil: 5  Number of cycles: 1   Amplitude = 150 
     coil: 6  Number of cycles: 1   Amplitude = 300 
     coil: 7  Number of cycles: 1   Amplitude = 30 
     
    I updated these defaults in the BMW code, so they should be robust over IOC 
    reboots.
    
    Figure 1 below shows the amplitudes seen from this configuration, tested at the 
    end of 5772 and implemented from then on.
