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:

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 value of dV < 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 UFO Orbit v2.41 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 in two ways to the set of orbits (see also Kornoš et al., 2013): (a) criteria only applied to the final solution in the line UNIFIED; and (b) criteria applied to each line of a meteor – if some line does not fulfill the following criteria, the meteor is rejected:

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)

The EDMOND v5.03 database (created accroding to Kornoš et al. 2014a,b) contains orbital elements and geophysical data of 252 425 meteors from 2001 to 2015 (latest update 21.4.2016). The database is saved in csv and text format. The text version does not contain all items.
