Ramiro dAu Analysis
===================
He has produced pi,k,p, spectra from dst2spec, ie Flemming's package.  
He has min bias and 0-30%, 30_60%, 60_80%. He is trying to push  
beyound 2.0GeV and so has corrected his spectra for contamination. To  
create dN/dy's over a wide rapidity spectrum he has fit a Levi  
function using "Combined Fits" macro that was developed for the pp  
analysis. T = T0 + ay + by^2 and the same for the p0 parameter.

Getting the dN/dy versus rapidity he thinks he has some problems at  
12 and 8 degree, ie rapidity 2-3. There was also some discussion on  
the error values. There are significant fluctuation around the  
general curve and he thinks that a first fit that uses only settings  
with good low Pt data should be used. Then use all data where you  
allow just the dN/dy to be free.

For the protons he has fit to exponentials in Mt. He tends to have  
good coverage at low Pt so this helps with the dN/dy. At high Pt he  
may have contamination from pions and kaons.

d/p Michael
===========
The main topic was the discussion of the summary which is now perhaps  
too long. The distinction between radial and elliptic flow should be  
noted. There were several small comments on the text and  
unfortunately a few gremlins crept into the figures. These should be  
fixed this weekend so we can hopefully announce the paper soon.


pp paper: Flemming and Kris
===========================
Flemming quickly went through the draft pp paper, with special  
emphasis on the figures. There were several suggestions for improving  
the clarity of the figures and a few questions on the data and fits.
