KCDC Data Format for 'KASCADE' and 'COMBINED' Detectors

Common data format information for 'KASCADE' and 'COMBINED' DataShops

Available data formats for download

The data sets available via the KCDC DataShop are supplied in various file formats. Selectable by the user and depending on the quantities chosen, we offer for download:

  • ASCII - plain text format
  • ROOT - object oriented framework developed by CERN
  • HDF5 - hierarchical data format

The KCDC data sets released with WOLF359 and VULCAN have only been transferred in ASCII data format. Due to a rapidly increasing number of parameters and meta information we changed to HDF5 and ROOT file format respectively for coming releases.

ASCII will be provided only for non-array quantities. If an array quantity like ‘Muon Density’ or ‘Arrival Time’ is selected the ASCII format button will no longer be available.

ROOT is an object oriented framework developed by CERN aimed at solving the data analysis challenges of high energy physics.

HDF5 is a file format designed to store and organize large amounts of numerical data objects and a wide variety of metadata. HDF is a unique technology suite that makes possible the management of extremely large and complex data collections with no limit on the number or size of data objects.

Measured and simulated data

Measured and simulated data basically have the same data format. The differences are on the one hand that event parameters such as event time, temperature and air pressure are only available for measured data, while for simulated data event information such as primary particle, true shower direction or tue number of electrons, muons and so on are available from CORSIKA and CRES simulations.


Below are lists of quantities available for download with some of their properties
