  1.2. SW Plots
	Overall ICME quality index: 1
	SW type: MC+SH
	ICME signatures: Bmax: 13.1 nT
			 Smoothly changing Bz.
	Other ICME signatures: decreasing velocity, low density, low proton temperature, and low plasma beta
                     
	Peculiar behavior: 
                         
	Search Window:
	Upper bound: Disturbance speed 410 km/s: 102 hrs:
	Lower bound: Transit speed < 700 km/s: 60 hrs <

2. CME
   2.1. A. Candidate A
 	A.1. LASCO:
		#CME 2013/04/09 at 12:24 UT, partial halo (from CDAW)
	A.2. STEREO:
		CME was moving in the same direction in COR2-A and COR2-B,therefore wasn't moving in the front side.
	A.3. AIA and GOES:
	A.4. Comment:
		not the source of the disturbance.


   2.2. B. Candidate B
 	B.1. LASCO:
		#CME 2013/04/11 at 07:24 UT, halo (from CDAW)
		Major CME moving with 861 km/s velocity.
	B.2. STEREO:
		 partial halo in COR2-B and halo in COR2-A, front side moving CME.
	B.3. AIA and GOES:
		correspondig flare of M6.5 class from the AR 1719 at N07E13
	
	B.4. Comment:
		Likely the source of the disturbance.


   2.1. C. Candidate C
 	C.1. LASCO:
		#CME 2013/04/12 at 02:00 UT, partial halo (from CDAW)
		Major CME moving with 391 km/s
	C.2. STEREO:
		CME was moving in the same direction in COR2-A and COR2-B,therefore wasn't moving in the front side.
	C.3. AIA and GOES:
	C.4. Comment:
		not the source of the disturbance, because of direction and velocity. 


3. Other Comments
	Starting and ending time of disturbance and ejecta are different from GMU catalog.
