New & Modified Features

With the new release SKARAGAN 2.0 we updated all our software packages used. Furthermore, the offered simulations were supplemented by a further set, generated with the high-energy model SIBYLL. The outdated download procedure via ftp-download was replaced.

Sotware update

Based on the operating system UBUNT 20.04 LTS we now use:

• Django 3.1.4 ;

• PostgrSQL 12.6 ;

• nginx 1.18 ;

• Python 3.8.5 ;

• Celery 5.0.2 ;

• RabbitMQ 3.8.12 ;

• MongoDB 4.0.10 ;

• gunicorn 20-0-4 ;

• CERN ROOT 6.22/02 ;

• Javascript & jquery ;

Other changes

Concerning the new download procedure, we completely removed the ftp-download, as it is not supported by modern Web browsers anymore. The download is now processed directly via https. This procedure is valid for all downloads (user requests, Preselections, Simulations, programming examples etc.).

With this release we publish a new simulation set based on the cosmic ray event simulation package CORSIKA using the high-energy interaction model SIBYLL 2.3d with Fluka 2011 for particle energies below 200 GeV. The main change in the latest model is Sibyll 2.3d with regard to Sibyll 2.3c, is in the production of π⁰ in jets. In Sibyll 2.3c this production is strongly suppressed.

The data privacy policy statements have been updated and integrated in the 'Head Menu' bar to be more accessible.

User accounts

• • the user accounts have been cleaned in the sense that the users database was cleared from all users without login after 1.1.2020. For the remaining users the accounts remained untouched.

Security update

The new release NABOO 2.2 is meant to inform our users how KCDC meets the new Data Protection Regulations

On the ‘Regulations’ page a new part dealing with the Privacy Policy as been added.

New Features

In the new release NABOO 2.1 we have added spectra data from 21 Cosmic Ray Experiments

At present 88 data sets are available for download from 20 different experiments published between 1984 and 2018 in the energy range 10¹⁴ to 10²⁰ eV. In case of KASCADE and KASCADE-Grande we published as well the data sets from different mass groups like p, he, co, si and fe or heavy and light respectively derived from the unfolding procedure for different high energy interaction models like QGSJet, EPOS and SIBYLL.

The 'KCDC-Manual' comprises all nessessary information to handle the spectra data published.

New Features

In the new release NABOO 2.0 we have added CORSIKA simulations done for KASCADE for download together with a completely new 'KCDC-Simulations-Manual'

Details:
Concerning the simulations we provide 180 ROOT files for direct download separately for the three detector components KASCADE, GRANDE and CALORIMETER. Simulations are done for 6 different High Energy Models from three different model families:

• QGSjet-II-02 and QGSjet-II-04
• EPOS-1.99 and EPOS-LHC
• SIBYLL-2.1 and SIBYLL-2.3

The simulation ROOT data sets are based on the same data structure as the measured data released with NABOO 1.0 early this year. An additional ROOT Tree called "trmc" (True Monte Carlo Simulations) provides information on the true properties of the simulated events like 'true primary energy', 'true core position' and more.
The simulation pages can be invoked via the KCDC menu item 'Simulations'
To have access to the download area you have to be a registered user.

The 'KCDC-Simulations-Manual' comprises all nessessary information to handle the simulation data published.
