Thanks for the plot. Can you plot your cuts on top of the data? We did this very quickly here last fall and found netp around 40 at y~3, so our preliminary proton yield must be roughly a factor 4 higher than yours. At y~2, the difference looks to be about a factor of 2, while at mid rapidity, the diferences are small. I don't know how trustworthy the 40 is, but I think you will have problems with baryon number conservation if netp at y~3 is only around 10. I'll check the status of the local analysis, and see if anything has changed. Cheers, Ian On 22/3-2005, at 12:07, Ionut Christian Arsene wrote: > > Hi Ian, > > Thank you for your message.
