Files :
1) catalogue_2020_2022_VdA.csv (comma-separated) catalogue file contains: eventID, Date, Latitude, Err_Lat, Longitude, 
   Err_Lon, Depth, Err_Depth, Depth_Assigned, RMS, ML, Err_ML, Phases_Number, Stations_Number, GAP.
Where: 
    eventID: Unique identifier for the seismic event, string (e.g., cms-ingv2020enlzi).
    Date: Date and time (UTC) of the origin (YYYY-MM-DD HH:MM:SS).
    Latitude (°N), Err_Lat (km), Longitude(°E), Err_Lon (km), Depth (km), Err_Depth (km): Hypocentral coordinates and
    errors.
    Depth_Assigned: Flag "NaN" (calculated depth), "operator assigned" (fixed depth).
    RMS: Root Mean Square of travel-time residuals (s).
    ML, Err_ML: Local Magnitude and error.
    Phases_Number: Number of phases used for the location.
    Stations_Number: Number of stations that have at least one phase.
    GAP: Maximum azimuthal gap (°).

2) .xml (e.g., cms-ingv2020enlzi.xml), QuakeML (Schorlemmer et al., 2011), archive which includes preferred solution of event parameters,
   event ID, spatial and temporal coordinates of the hypocenter (latitude, longitude, depth, and origin time), associated P and S phase 
   picks, amplitudes, and station magnitudes associated for each event.

3) stations.txt (tab-separated) stations file containing geographic coordinates, elevation, and network affiliation of the monitoring stations 
   (STATION, LATITUDE, LONGITUDE, ELEVATION and NETWORK), where latitude and longitude are in decimal degrees (deg), elevation in m a.s.l., 
   and network codes are those assigned by the International Federation of Digital Seismograph Networks (FDSN):
    VA = Monitoring seismic network of the ‘Val d’Agri’ oil field
    IX = Irpinia Seismic Network
    GE = GEOFON
    VD = High Agri Valley geophysical Observatory
    TP = Monitoring seismic network of the ‘Gorgoglione’ oil field
    IV = Italian National Seismic Network
