1 There are two shocks ahead of the MC. The shock-MC association is 
 1  ambiguous. 
 2 Possible radio emission but may not be associated with this shock. 
 3 Wind/WAVES type II date is one day after the CME date.
 4 CME solar source identification has less confidence, which is possibly 
 4  associated with a large interconnecting loop between NOAA 8126 (N20E48)
 4  and NOAA 8124 (S20E10) on 1997/12/26 observed by SXT.
 5 Ejecta identification has less confidence.
 6 CME association has less confidence, i.e., other possible candidate 
 6 CMEs exit.
 7 Possible radio emission; association with this shock has less 
 7  confidence. 
 8 Possible radio emission. 
 9 Wind/WAVES type II date is two days after the CME date.
10 There may be a faint halo not measured. The solar source is a C2.9 
10  flare from AR8477 (S24W03) on 1999/03/07 at 03:54 UT.
11 MC event. Low confidence on CME association. The solar source may be 
11  correct, but the CME is too faint to be measured.
12 Wind/WAVES type II burst is on 2000/02/11.      
13 CME has uncertain width (possible halo CME).
14 Radio emission may be associated with an earlier CME. 
15 CME is unmeasured. Solar source is possibly associated with a M3.7 
15  flare at AR9087 S13W71 on 2000/07/25 04:40 UT.
16 CME width is uncertain due to the compound CME.
17 Multiple eruptions from N20E12 and N11W11.
18 Multiple C3.2 flares are from N02W02 and N25E17.
19 CME is associated with a filament eruption.
20 Possible short ejecta (1-2 hours) after 24 hours of the shock, which 
20  may not be associated with this event. 
21 CME may be backsided. Possible alternative candidate is the CME on 
21  2001/03/15 at 22:26 UT.
22 Data gap from ~17:00 to ~19:00 UT, possible radio emission. 
23 Ejecta association has less confidence. Ejecta after > 24 hours from 
23  the shock.
24 Alternative candidate is the CME on 2001/05/24 at 20:26 UT associated 
24  with the M1.2 flare on 05/24 at 19:30 UT from N07E29 (AR 9468).
25 Listed as a magnetic cloud-like event in 
25  http://lepmfi.gsfc.nasa.gov/mfi/MCL1.html
26 Clear radio emission but may not be associated with this shock.
27 Ejecta identification has less confidence. Ejecta is a marginal event.
28 MC event. CME is too faint to be measured. Solar source is a C6.3 
28  flare from AR9678 (N06W02) on 2001/10/27 at 08:05 UT.
29 Possible complex event. Several low-beta intervals. 
30 Possible complex event. MC onset after >24 hours from the shock.
31 Alternative candidate is the faint partial halo CME on 2002/07/29 at
31  00:30 UT from S22W11 (AR 10044).
32 It is possible that the previous CME candidate on 2002/07/29 at 
32  12:07 UT is associated with the 2002/08/01 shock at 23:05 UT.
33 Shock identification has less confidence.
34 Proton temperature drop over a short interval (1 - 2 hrs) followed by 
34  high speed stream.
35 Metric type II burst is on 2004/12/02.
36 Alternative candidate is the CME on 2005/05/16 at 13:50 UT from N13W29.
37 Alternative candidate is the CME on 2005/06/07 at 10:24 UT from N25E20.
38 MC event. CME is too faint to be measured. Solar source is an EUV 
38  eruption on 2005/07/15 at 15:00 UT, location S15W29.
39 CME is too faint to measure. Solar source is possibly associated with 
39  a large faint arcade formation at S40E28 on 2006/04/10 ~21h by SXI. 
39  LASCO/C2 observed a faint spray-like front sweeping out the streamer at
39  early 04/11. An alternate candidate is the CME on 04/10 at 06:06 UT 
39  whose south-east part may be backsided and south-west part may come 
39  from AR 10869 (S12W22).
40 CME is too faint to measure. Solar source is possibly associated with 
40  a cusp structure at S13E37 on 2006/08/11 ~19:31h by SXI. LASCO/C2 
40  observed a large scale dimming overlaping the cusp arcade later.
41 Shock and CME source (flare association) identifications have less 
41  confidence.
