Dear Workshop participants,

As you know the organizers were planning to have a strong "workshop"
component with a detailed discussion of the HBT data and their theoretical
interpretation. Ron Soltz and Yiota Foka who took on themselves the task
to get the data presentation at Trento organized had many discussions
among each other and with the experimentalist participants affected by
this plan. It turned out that the originally planned format was too
ambitious, in particular for the CERN collaborations. However, we are not
willing to give up: We still think that we should make a strong effort to
actively work on the data, trying to understand howe everybody deals with
their data, what are the analysis procedures, what are everybody's
"tricks" (which you may try on your own data later), etc. --- all in all,
to get familiar with each other and each others' methods, and to better
understand their results and how they were extracted.

To achieve this goal requires a MINIMAL effort from every participant who
will show or bring data, which Ron has listed for you below. Since in
accepting the invitation to Trento you agreed to actively collaborate
versus this goal I am sure you will all find it not too hard to
comply with our requests detailed below. As you can see from the
preliminary program on the HBT96 home page, we have set aside twice
3 hours and 3 times 2 hours for data discussion (outside and in
addition to the seminar presentations) -- so your efforts will be
rewarded by active interest from everybody during these time periods. 

We are looking forward to working with you at the workshop, and hear what
you have to say!

Best regards,

Ulrich Heinz

               *** Request of Participants ***
**********************************************************************

	Any experimentalist, theorist, or any participant that will
show experimental data and/or model results must be willing to provide
the following for every plot to be shown.

1. Text of numbers for correlation functions and fits.
   Colliding system:            Beam energy:
   Acceptance (Y-Pt):           Trigger condition:
   Particle ID definition:      2-Particle cuts/corrections:
   Kinematic cuts:	        Reference frame:
   Fit function:                Fit parameters and errors:
   Correlation contours for parameters (at least one fit): 
    
2. Histograms for any plots to be shown at workshop.  
   Separate histograms for raw data, fully corrected data, and for
   each correction applied should be left on a disk accessible via ftp
   or brought to the workshop on 8mm tape in tar or cpio format.
   Format for histograms can be ascii or hbook. 

3. If space and analysis mothods permit, ntuples on disk at home.
   If the internet connection is not too slow, we intend to provide
   time for remote real time analysis from Il Trento.
