== Description ==
:: First C2 Appearance - Taken from the SOHO/LASCO CME Catalog
:: Location (Apparent Loc) - Latitude and longitude of CME source region in the heliographic coordinate. The latitude and longitude in parentheses indicates the source region location without solar b angle correction.
:: DSC - Projected distance on the plane-of-sky from the solar center to CME source region.
:: SPA - Position angle of CME apparent location.
:: CPA - Central position angle.
:: MPA - Measurement position angle.
:: Width - Angular width.
:: Speed - Linear speed.
:: Acc - Acceleration.
:: Def - Deflection. E: Equator-ward, P: Pole-ward, R: Radial event.
:: EIT Ref-Time - A time when the EIT image shows CME initiation clearly.
:: CL - The confidence level of the identification.
:: The parameters in the columns 2, 6, 7, 8 and 9 are adopted from CDAW CME Catalog.

== The LIST OF CME SOURCE LOCATIONS is generated ==
:: by the members of STEP Team at USTC: Yuming Wang, Caixia Chen, Bin Gui, Chenglong Shen and Pinzhong Ye
:: based on the SOHO/LASCO CME CATALOG generated and maintained at the CDAW Data Center by NASA and
The Catholic University of America in cooperation with the Naval Research Laboratory
:: and the SOHO/EIT MVI movies generated by the Naval Research Laboratory.
:: Comments or questions about this list could be addressed to Dr. Yuming Wang (ymwang@ustc.edu.cn),
:: or written here.
