Nowadays, due to the international cooperation, meteor activity is monitored over almost the entire Europe. Consequently, in recent years, multi-national networks of video meteor observers have contributed many new data. At present, there are 4 655 640 individual meteor records (from 2000 to 2016) in the EDMOND database, of which 592 699 multi-station orbits (so-called Q0 orbits or raw orbits) have been created. As a result, the latest version of EDMOND database (v5.04, February 2018) contains 322 566 orbits collected from 2001 to 2016. The EDMOND catalogue of meteor orbits is created by using the software UFO Orbit v2.41. The application imports all data in the UFO format. This means that all data obtained and analyzed by UFO tools can be used without any change. However, data obtained by the MetRec software have to be converted into the UFO format, using the program INF2MCSV written by SonotaCo. In the program UFO Orbit v2.41, all combinations of meteors in a time interval dt < 5 s are created. For these combinations, the level Q0 is set and some other additional conditions also have to be set (parameters are defined in the UFOOrbit Manual):
• dur > 0.1 s (duration of the meteor)
• dt < 5 s (maximum time difference between 2 stations)
• GD < 10 km (minimum ground distance between 2 stations)
• Gm% > -100% (overlap of a meteor sighting from two stations)
• 15 km < H1 < 200 km (beginning height)
• H2 < 200 km (terminal height)
• QA > 0.15 (empirical quality parameter within the interval [0,1])
• dV < 7 km/s (the largest difference in velocity between stations considered to compute the orbit)
The last condition is the most important modification in comparison to the previous versions of the database. The value of 7 km/s is about 10% of the largest geocentric velocity of a bound object (unfortunately, it is not possible to set directly the value of 10%). In this way, most false meteors are eliminated. The output from UFOOrbit is a set of orbits which contains preliminary orbits computed for each station of the considered meteor and also a mean UNIFIED orbit as a final solution. To reject less precise orbits and also to eliminate the rest of false orbits, another filter is applied to the set of orbits (see also Kornoš et al. 2013):
• Q0 > 1.0° (observed trajectory angle)
• Qc > 10° (angle of convergence)
• dGP < 0.5° (distance between two poles of the orbit)
• dv12% < 7.07% (difference in geocentric velocity between the unified result and one of the considered stations)
