Hi,

I was having problems sending email to the VeryStrange group. I think it 
had to do with attaching too many plots.

I apologize if you are receiving redundant emails from me.

I have plots for beta vs. momentum.

* Phythia determined background events:

* Omega- events:

As can be seen on the plots, the majority of the kaons for Omega 
production have momentum less than 2 GeV/c.

I have plots for the gamma p -> k+ k+ k0 Omega- where 3 kaons are seen

:
The cross section versus photon energy with estimated error bars. Since 
the cross section was locked to 0.3 nb, this is not a very interesting 
plot.

:
This is the counts as a function of photon energy and center of mass 
angle.

I'll try and get the same plots for the cascades but I probably won't be 
able to get around to that until Friday.

Take care,
Michael
