AIRES release notes.

These notes briefly summarize the new developments and/or improvements of the current version of AIRES. For more detailed information on any of these new features, refer to the user's manual and/or the demo files that come with the corresponding AIRES distribution.

Release notes for AIRES 19.04.10.

Output data and analysis tools

Python interface. All the modules that make the AIRES shared object library can now be called from a Python environment in s simple way. This feature of AIRES makes it possible, among other applications, to analyse output from AIRES simulations (even old output files created with AIRES versions prior to 19.04.10) by means of Python scripts/programs, therefore allowing Python programmers to take advantage simultaneously of a clear and powerful object-oriented programming language like Python, and the speed and stability of AIRES library routines that can fastly scan compressed output files with millions of particle entries. For details read the file AIRES-Python-README.txt included in the AIRES distribution (see inside the doc directory).

Bugs

Some minor technical bugs with no appreciable effects on the physical algorithms have been fixed.

Release notes for AIRES 19.04.08.

Bugs

Correction of a bug related with the interface of AIRES with the hadronic collision packages EPOS and SIBYLL (many thanks to Jaime Alvarez-Muñiz, Henk Brans, Roberta Colalillo, Eva Santos, and Matías Tueros).

Release notes for AIRES 19.04.06.

Algorithm modifications

Hadronic collision external packages.

This new release of AIRES includes the newest versions of EPOS and SIBYLL.

Bugs

Several problems with AIRES 19.04.00 simulation program were detected or reported by several users. All the errors in the program's code -mostly minor bugs- were fixed and are no longer present in the current version of AIRES. Some of those bugs are:

• Correction of a checkpoint/restart bug related with function grandom (bug found thanks to M. Tueros). Now the status of grandom is also saved into the idf file.
• Correction of a bug related with error message initialization in some auxiliary programs (thanks to an indication by M. Tueros).

Release notes for AIRES 19.04.00.

Algorithm modifications

Atmosphere.

All the code related with the atmospheric model management has been carefully reviewed. New atmospheric profile models, namely SouthPoleAvg and MalargueAvg, are now available (see directive Atmosphere), corresponding to annual averages of atmospheric profiles of the South Pole and Malargue sites, respectively. Additionally, the new directive AddAtmosModel allows the user to define custom atmospheric models that can be used alternatively to the built-in models.

Neutrinos.

New tables available (6296, 6496, and 6796) that record the number and energy of created secondary neutrinos as a function of atmospheric depth.

Dynamic setting of primary energy.

The special primary modules are now capable of setting the shower primary energy dynamically at the moment they are invoked to inject the special primary particles (the PrimaryEnergy IDL directive is no more mandatory in such cases).

Installation procedure

• The installation procedure now supports the installation of extensions to the AIRES programs.
• A series of utility programs and special particle modules are automatically build during the installation procedure, for example:
  • acfreccount. Utility to count the number of records of a given AIRES compressed file (.grdpcles or .lgtpcles).
  • acfscan. Scans a given AIRES compressed file and returns information about the data it contains.
  • airescode2pname, pname2airescode. AIRES code from particle name, and vice-versa (e.g., "pname2airescode pi+" returns "11"; "airescode2pname 11" returns "pi+").
  • mergeciofiles. Combine the data contained within various AIRES compressed files onto a single file.
  • specialprim0. The special particle module used in the "specialprimdemo" (basic special particle demo).
  • multiprims. The special particle module used in the multiprimary shower demos, that allow to easily simulate showers with many primary particles.

Input Directive Language

New features.

• The site TelescArray was included to the default site library, and can be selected by means of the Site directive.
• New built-in atmospheric models SouthPoleAvg and MalargueAvg are available. They can be selected using the Atmosphere directive.

New directives.

• AddAtmosModel.

Directives that changed their syntax or behavior.

• AddSpecialParticle.
• Atmosphere.
• Input.
• InputPath.
• Shell.

Output data

New output tables.

The current AIRES version includes 4 new tables:

• 0100. Atmospheric profile.
• 6296. Number of created particles: All neutrinos.
• 6496. Number of created entries: All neutrinos.
• 6796. Energy of created particles: All neutrinos.
