The catalogue consists of two parts. The first part contains the global physical classification (PE, Pf, and KB criteria) for each modeled Geminid in a single file (geminids.dat). The second part consists of individual files for each Geminid, located in a directory called data and listed in a file called gem_data.dat. Two or three files containing a meteor code in their names provide light curves (*.lc, magnitude as a function of time, length, and height), radiometric curves (*.rlc, magnitude as a function of time) for bolides and a few meteors, as well as dynamical data (*.inp, time-length-height data points). In geminids.dat, the '-' character implies a non-existent value. In radiometric curves, the value of e_mag=99.99 indicates that the error was not calculated for this data point. Empty lines in RLC, LC, and INP files separate measurements from different stations. Each data file contains a single-line header starting with '#' character with the name of each column. The light curve data, radiometric data, and dynamics data contain the following quantities. Relative time is time measured from an arbitrary initial time instant common to all stations. The absolute brightness of a meteor is measured in magnitudes (calculated from the measured brightness and calibrated for a distance of 100 km from the station), and the magnitude error represents the uncertainty of the measured brightness. Length is the distance along the trajectory of a meteor measured from the meteor's beginning position measured typically from the closest station. The height is an altitude above ground level calculated using triangulation of the trajectory of a meteor observed from several stations. The length and height in INP files are measured values for the given time mark or video frame. These data were used for the modeling of the dynamics. The length and height in the LC file are smoothed values from a preliminary time-length fit (not considering fragmentation). These data are provided just for the purpose of plotting brightness as a function of length or height.
