Query: Near-Sun Flux Rope Structure of CMEs   We have used the Krall flux-rope model (Krall and St. Cyr, Astrophys. J.
2006, 657, 1740) (KFR) to fit 23 magnetic cloud (MC)-CMEs and 30 non-cloud
ejecta (EJ)-CMEs in the Living With a Star (LWS) Coordinated Data Analysis
Workshop (CDAW) 2011 list. The KFR-fit results shows that the CMEs associated
with MCs (EJs) have been deflected closer to (away from) the solar disk center
(DC), likely by both the intrinsic magnetic structures inside an active region
(AR) and ambient magnetic structures (e.g. nearby ARs, coronal holes, and
streamers, etc.). The mean propagation latitudes and longitudes of the EJ-CMEs
(18, 11) were larger than those of the MC-CMEs (11, 6) by 7 and 5,
respectively. Furthermore, the KFR-fit widths showed that the MC- CMEs are
wider than the EJ-CMEs. The mean fitting face-on width and edge-on width of the
MC-CMEs (EJ-CMEs) were 87 (85) and 70 (63), respectively. The deflection away
from DC and narrower angular widths of the EJ-CMEs have caused the observing
spacecraft to pass over only their flanks and miss the central flux-rope
structures. The results of this work support the idea that all CMEs have a
flux-rope structure.
