Phantom 3 SE log problems

I export my log of Phantom 3 SE to a .csv file, and I hope to know the meaning of indexs in the file as follows:

1.AirCraftCondition_craft_flight_mode
2.AirCraftCondition_launch_acc_duration
3.connected
4.ctrl_vert_vert_module_module_mode
5.ctrl_vert_vert_thrust_cmd_id
6.ctrl_vert_vert_vel_cmd_before_limit
7.imu_raw_xxxxcnt
8.RC_Rudder
9.svo_ctrl_debug_svo_avoid_debug2_limit_norm
10.usonic_usonic_flag

Thanks so much
