RMSE and CORR for predicted Kp using ACE Level 2 data (L2) and ACE real-time data (RT) as inputs for the period 1 April 2011 to 1 March 2013. Coverage indicates whether samples corresponding to timestamps of the L2 or RT set have been used in computing RMSE and CORR. Median indicates whether the 5-minute median filter ton and V has been applied.
