About

This program tries to reconstruct the trajectory and position of a fireball given observer's data.

Program reads the data from a text file. The default is 'data.txt'. It can be overriden by passing a file name as an argument.

Output on current test data looks something like that (longitude's sigma and velocity is broken for now):

Answer:
  Location:
    lat =   35.2444 ± 0.0135(°)
    lon =   33.4917 ±    inf(°)
    z   =   17.7726 ± 0.3933(km)
  Velocity:  105.093(km/s)
    Local:
      v_East  =   -37.928(km/s)
      v_North =    30.632(km/s)
      v_z     =   -93.100(km/s)
    Global:
      v_x =  -57.223(km/s)
      v_y =  -83.342(km/s)
      v_z =  -28.708(km/s)
