-# FastJet release 3.0.6
-# M. Cacciari, G.P. Salam and G. Soyez
-# A software package for jet finding and analysis at colliders
-# http://fastjet.fr
-#
-# Please cite EPJC72(2012)1896 [arXiv:1111.6097] if you use this package
-# for scientific work and optionally PLB641(2006)57 [hep-ph/0512210].
-#
-# FastJet is provided without warranty under the terms of the GNU GPLv2.
-# It uses T. Chan's closest pair algorithm, S. Fortune's Voronoi code
-# and 3rd party plugin jet algorithms. See COPYING file for details.

+
+ * example_advanced_usage.ref:
+ updated reference output file following the bugfix (missing
+ "grooming mode" initialisation in one of the SoftDrop ctors) on
+ 2017-08-01
+
+ * RecursiveSymmetryCutBase.cc:
+ removed redundent code
+
2017-08-10 Gregory Soyez <soyez@fastjet.fr>
* RecursiveSoftDrop.cc:
fixed trivial typo in variable name
2017-08-04 Gregory Soyez <soyez@fastjet.fr>
* RecursiveSoftDrop.cc:
do not impose an angular cut in IterativeSD if it is -ve.
2017-08-01 Gregory Soyez <soyez@fastjet.fr>
* example_recursive_softdrop.cc:
added a series of optional flags
* RecursiveSoftDrop.cc:
fixed a few issues with the fixed depth version
* RecursiveSymmetryCutBase.hh:
a jet is now considered as havig substructure if deltaR>0
(coherent with released version)
* SoftDrop.hh:
bugfix: set the "grooming mode" by default in all ctors
+ EDIT: caused issue with make check, fixed on 2017-09-069 (see
+ above)
* RecursiveSoftDrop.{hh,cc}:
added support for the "same depth" variant
* RecursiveSymmetryCutBase.cc:
also associate a RecursiveSymmetryCutBase::StructureType structure
to the result jet in case it is just a single particle (in
grooming mode)
2017-07-31 Gregory Soyez <soyez@fastjet.fr>
* RecursiveSymmetryCutBase.{hh,cc}:
added the option to pass an extra parameter to the symmetry cut
function
* RecursiveSymmetryCutBase.{hh,cc}:
* ModifiedMassDropTagger.hh
* SoftDrop.hh:
minor adaptions due to the above change + added a few methods to
query the class information (symmetry cut, beta, ...)
* RecursiveSoftDrop.{hh,cc}:
Added support for
- a dynamical R0
- recursing only in the hardest branch
- imposing a min deltaR cut
Added a tentative IterativeSoftDrop class
2017-07-28 Gregory Soyez <soyez@fastjet.fr>
* RecursiveSoftDrop.cc:
adapted to the latest changes in RecursiveSymmetryCutBase
* RecursiveSymmetryCutBase.{hh,cc}:
reorganised the output of the recursion step (recurse_one_step)
using an enum to make iot more readable (and to fix issues where
the dropped prong is actually 0, e.g. after subtraction)
2017-07-26 Gregory Soyez <soyez@fastjet.fr>
* example_recursive_softdrop.cc: *** ADDED ***
added a draft example for the use of RecursiveSoftDrop
* RecursiveSoftDrop.{hh,cc}: *** ADDED ***
added a first pass at an implementation of RecursiveSoftDrop.
This is based on Frederic's initial version but keeps the
branching structure of the jet. Some of the features, like
dynamical R0, direct access to the substructure or the same depth
variant, are still unsupported.
* SoftDrop.hh:
declared _beta, _symmetry_cut and _R0sqr as protected (was
private) so they ca n be used by RecursiveSoftDrop
* RecursiveSymmetryCutBase.{hh,cc}:
extracted from result() the part that performs one step of the
resursion (implemented as recurse_one_step()). This is repeatedly
called by result(). It has specific conventions to indicate
whether or not some substructure has been found or if one ran into
some issue.

* Merging the development branch 1.0-beta1-softdrop-addition back

added a 'single' ctor argument [true by default]. When true, the
hardest jet after reclustering is returned, otherwise, the result

branch started at revision 611 to start including SoftDrop in the
Recursivetols contrib
2014-04-24 Gregory Soyez <soyez@fastjet.fr>
* ModifiedMassDropTagger.hh:
added a mention of the fact that when result is called in the
presence of a subtractor, then the output is a subtracted
PseudoJet.
* ModifiedMassDropTagger.hh:
declared _symmetry_cut as protected (rather than provate) so it
can be accessed if symmetry_cut_description() is overloaded.
* example.cc:
trivial typo fixed in a comment
2014-02-04 Gavin Salam <gavin.salam@cern.ch>
* VERSION:
upped it to 1.0-beta1

added an #if to make sure FJ3.1 features are only used if FJ3.1
is available. (Currently FJ3.1 is only available to FJ developers).
2014-01-26 Gavin Salam <gavin.salam@cern.ch>
* VERSION:
renamed to 1.0-beta0
* ModifiedMassDropTagger.hh:
* README:
added info on author names
* example_mmdt_sub.ref: *** ADDED ***
added reference output for the pileup test.
2014-01-25 Gavin Salam <gavin.salam@cern.ch>
* example_mmdt_sub.cc:
* Makefile:
added an extra example illustrating functionality with pileup
subtraction.
2014-01-24 Gavin Salam <gavin.salam@cern.ch>
* ModifiedMassDropTagger.cc:
Reorganised code so that (sub)jet.m2()>0 check is only used when
absolutely necessary: so if using a scalar_z symmetry measure,
whenever scalar_z < zcut, then there is no point checking the mu
condition. This means that there's no issue if the (sub)jet mass
is negative, and one simply recurses down into the jet. (Whereas
before it would bail out, reducing the tagging efficiency).
Also removed the verbose code.
2014-01-23 Gavin Salam <gavin.salam@cern.ch>
* ModifiedMassDropTagger.cc|hh:
* example.cc
replaced "asymmetry" with "symmetry" in a number of places;
implemented the structural information and added it to the example;
added a new simplified constructor;
improved doxygen documentation;
started renaming -> RecursiveTools
* README
some tidying
* VERSION
1.0-b0
2014-01-22 Gavin Salam <gavin.salam@cern.ch>
* ModifiedMassDropTagger.cc (contrib):
-ve mass now bails out also when using the "y" asymmetry measure.
Also, default my is now infinite.
2014-01-20 Gavin Salam <gavin.salam@cern.ch> + Gregory
* ModifiedMassDropTagger.cc|hh:
introduced a virtual asymmetry_cut_fn (essentially a
dummy function returning a constant), to allow for derived classes
to do fancier things.
added warning about non-C/A clustering.
explicitly labelled some (inherited) virtual functions as
virtual.
2014-01-20 Gavin Salam <gavin.salam@cern.ch>
* example.ref:
* example.cc (main):
got a first working example and make check setup.
* ModifiedMassDropTagger.cc|hh:
improved doxygen comments;
added option whereby input jet is assumed already subtracted
2014-01-19 Gavin Salam <gavin.salam@cern.ch>
* ModifiedMassDropTagger.cc|hh:
* many other files
Initial creation, with basic code for MMDT
