HESS Public Test Release 1
High Energy Stereoscopic System (H.E.S.S.) is a system of imaging
atmospheric Cherenkov telescopes (IACTs) for the investigation of cosmic
gamma rays in the photon energy range of 80 GeV to 100 TeV. The data
published here is a list of estimated parameters of gamma-ray candidates,
i.e. particles for which it was determined with a high likelihood that they
are not cosmic-ray background, but gamma rays.
The provided parameters are:
* incoming direction as position in the sky
* energy
* likelihood of being a gamma ray
* run number
The data are taken in runs of 28 minutes. For each run, the data of all
auxiliary systems are recorded and links to air shower simulations and
lookup tables corresponsing to the environment and state of the instrument
are provided.

Full documentation on the dataset published here is available at
https://hess.science/hess_dl3_dr1_v0.6.pdf.
The data and documentation is publicly released by the H.E.S.S.
collaboration as a contribution to the ongoing efforts to define a common
open format for data level 3 of imaging atmospheric Cherenkov telescopes
(IACTs) and IACT open-source science tool development, to enlarge the
community involved in IACT data analysis.
No scientific publications may be derived from the data. Using the data for
new claims about the astrophysical sources is not permitted.
When using this data, please include the following attribution:
This work made use of data from the H.E.S.S. DL3 public test
data release 1 (HESS DL3 DR1, H.E.S.S. collaboration, 2018).
H.E.S.S. observes in bunches of 18 minutes,
and each bunch is characterised by some metadata. This metadata
is kept in this table and accessible through the obs_id column.
