1. ESA no. This is the spacecraft ID used in Cluster operations by ESOC and JSOC.
2. COSPAR ID (also known as the International Designation). This ID is assigned by World Data Center A for Rockets and Satellites at NASA Goddard Space Flight Center following spacecraft launch. It is the unique designator that is required for all spacecraft under international law. It takes the form YYYY-LLLI, where YYYY is the year of launch, LLL is the launch number and I is a letter that distinguishes the different items launched.
3. USSPACECOM catalogue number (also known as the NORAD catalogue number). This is the catalogue number assigned by NORAD when an object is first tracked.
4. CSDS code. This is the two-character spacecraft code used in the data products produced by the Cluster Science Data System (CSDS).
5. ESOC FD code. This is the two-character spacecraft code used in the names of orbit and event files produced by ESOC Flight Dynamics.
6. ESA Flight Model number. These are the numbers used by ESA during the construction and ground testing of the Cluster-II spacecraft. Note that this sequence follows on from that used for the construction and ground testing of the original Cluster-I spacecraft.
7. Symbols. The first set of symbols are made out of line segments, whereas the second set may be either outlines or solid-filled. Note that asterisks have 6 legs and stars have 5 points.
