DAFNE is :
DAFNE runs immediately after the XSDST
production by DSTANA and has as outputs the XSDST files
corresponding to the different data streams, with all the DAFNE tagging
results stored in the pilot record.
In addition, ASCII event list files (the scanning lists) are
produced. The scanning lists contain the tagging
results event per event. They can be used to scan the events
with a certain tag and are used to provide the
hotline statistics information.
The program consists of:
A package for tagging of interesting events
(as input to visual scanning) and hotline analysis
A tool for fast checking of data (physical and technical)
A filter that performs event selection and defines the different
data streams existing in DELPHI
DAFNE (Delphi Analysis code to Flag New Events)
was first used in the LEP run at central mass energy of
130 GeV (November 1995) and many people contributed to its development.
Since 97 the DAFNE DST is the reference
for analysis. Before the 1999 run, the need to "refresh"
DAFNE became universally felt. The main code was simplified and moved to
SKELANA, the topological
treatment was developed and the set of tagging routines was reduced.
The main code
which accesses the (XS)DST information using SKELANA, performs
the steering of the taggings and
the streaming of the events. The main DAFNE code performs also a set
of basic analysis tasks:
More details can be found HERE
A topological classification of the events (according to the
nb. of isolated particles and jets)
The computation of useful global event variables
The flagging (to be used as a "veto") of certain categories
of events, namely Bhabhas, Comptons, gamma gamma fusion, ...
A set of tagging routines provided by the users to
select a certain category of events
information on the DAFNE tagging routines, both user and internal
tags, can be found below.
The information needed for understanding the scan lists is provided here.
For the moment no specific routine pages are available, but they are vary
Where is the code ?
The DAFNE code and all the tagging routines are stored in:
