    Hi Itow-san,
    
    I added a link to zbs files and a summary of mis-reconstructed events in 
    my web page ( http://ale.physics.sunysb.edu/~sarrat/K2K/public/index.html ).
    I also included postscript files of event display for non 1R events in 
    electron sample.
    You can also download now the plots for each sample separately.
    
    Regarding your point 1), the 1D likelihood distributions are in the page 
    3 of the postscript files I posted yesterday (in the file plot.tgz).
    
    Regarding 2), I modified fdktntuple_superlight to include probth and 
    probpt (thanks Asia for the advice).
    Now, I need enough space to run bigger samples... My /home @ suketto is 
    nearly full. I think I'll need about 4Go, do you know where I can store 
    this ?
    
    Best,
    
        Antony
