"DESCRIPTION",
"This is a unique number that is used to create a sequential index (within each Study number) for this table. This is the second index of the table. Although dcmEventNumber could be used as the second index, it would require a larger number of bits to store an event since an index cannot be assigned a value of zero and thus would have to start at one. For example, a study with two events (Event # 1, Event # 2, (note that Event # 0 cannot be used)) would have to use two bits in each event record rather than one (two bits are required to represent the number 2 for Event # 2). Using Event Config # as a separate index provides for the least number of bits to be stored in the event data record."
