BLUE =

Estimate
Overview
This is the homepage of my BLUE
project.
It contains the up-to-date information about this
ROOT implementation of
the BLUE combination. Please refer to
the latest manual for details on the implementation.
For those having access to a computer on which ROOT is installed,
the suggested way to run the BLUE
package is to follow the section "Hints on the software
installation" in the manual.
Usage on computers without a ROOT installation
The ROOT package developed at CERN
is available directly
as source or
binary files,
via Github, or as
a Docker
container.
As an example, the workflow when
using singularity (see also the
Ubuntu
package singularity-container)
is:
- singularity -d pull docker://rootproject/root-ubuntu16
- singularity shell root-ubuntu16.simg
This container has a size of about 570Mb. From here onwards the
situation is almost identical to a computer having a ROOT
installation. Consequently, again it is suggested to follow the
section "Hints on the software installation" of the manual with
ROOTSYS=/usr/local/ of the container.
One natural caveat is that the container does not include a LaTeX
installation, such that further LaTeX file processing of files
generated by the BLUE software need to
be performed outside of the container.
For all examples shipped with the BLUE
software package (Release 2.3.0), it has been verified that the
results obtained with the ROOT Release 6.12/07 of the
container agree with those obtained with the present ROOT Pro
Release 6.18/04.
License and feedback
The BLUE software package is freely
distributed under the GNU Lesser General Public License. It has been
written with care, still mistakes are not excluded and it comes
without warranty.
A number of example functions are provided that reproduce published
combination results, and at the same time demonstrate the software
usage.
Please inform me should you find mistakes or pecularities. Please
give reference to Refs. [1, 2] should you base public results on
this software. Should you have any question or suggestion please do
not hesitate to send me a message.
Updates are planned on an irregular basis. If you want to be
promptly infomed about this via e-mail, please send me a message.
