    Ok, from the archives I gather that
    'Howdy, all Y'all'
    is correct? It's not easy being foreign ;-)

    Done, now in CVS.

    Almost done. This prompted me to recheck my calc. of the offset since I
    now have higher statistics, and I get a slightly higher value - 27.6
    cm. This number is now the default in CVS, set in the
    constructor. I include a ps-file showing the histo I used to det. this
    value - it allready has an offset of 26.5 in it, so I added the extra 1.1
    I get from the mean of the signal gaussian. Please have a look at it and
    see if it is sensible, since this offset is quite important. 
    
    Also, I guess we should really check what Michael is saying about the
    temp./time dependence of this offset... For reference, the included
    histogram has data from runs 2529, 2530, 2531 and 2535.
    
    Ping :-)
