magid 
Base Entity  assocamm 
Attribute Name  magid 
Logical Rolename   
ColumnName  magid 
RoleName   
Definition  Magnitude identifier. This key is used to identify a magnitude in the Netmag relation. It is required for every magnitude 
Note  Range: magid > 0 

ampid 
Base Entity  assocamm 
Attribute Name  ampid 
Logical Rolename   
ColumnName  ampid 
RoleName   
Definition  Amplitude identification. Each amplitude is assigned a unique positive integer identifying it. This number is used in the AssocAmO relation along with the origin identifier to link Amp and Origin. This number is used also in the AssocAmM relation along with the magnitude identifier to link Amp and Netmag 
Note  Range: ampid > 0 

commid 
Base Entity  assocamm 
Attribute Name  commid 
Logical Rolename   
ColumnName  commid 
RoleName   
Definition  Comment identification. This is a key used to point to free-form comments entered in the Remark relation. These comments store additional information about a tuple in another relation. Within the Remark relation, there may be many tuples with the same commid and different lineno, but the same commid will appear in only one other tuple among the rest of the relations in the database 
Note  Range: commid > 0

subsource 
Base Entity  assocamm 
Attribute Name  subsource 
Logical Rolename   
ColumnName  subsource 
RoleName   
Definition  A second identifier to specify the system or process that derived the data. e.g., the origin's AUTH is CI, but the subsource (the solution) was computed by JIGGLE 
Note  Range: Any free-format string up to 8 characters 

weight 
Base Entity  assocamm 
Attribute Name  weight 
Logical Rolename   
ColumnName  weight 
RoleName

importance 
Base Entity  assocamm 
Attribute Name  importance 
Logical Rolename   
ColumnName  importance 
RoleName   
Definition  This attribute denotes the importance of a phase/amplitude reading towards an origin/magnitude. 0.0 means no importance, 1.0 implies extremely important
