[Brahms-l] Re: Thursdays analysis meeting

I have put my tomorrow's presentation on hte web in the agenda.
I hope that the explanation of triggers will be satisfactory for all
now;)
I also enclosed few plots answering the problem below (thank you Ramiro
for the data).

Greetings from Krakow.

Radek

ps. it is probable that the presentation will be slightly different
tomorrow - if
I will find my mistake I will put additiional slide there.
