Labels in GraceDB

Labels are applied to events and superevents in GraceDB to indicate the state of that object. Some labels signify that an action is requested, while others signify that a follow-up process has completed and/or what the result of a follow-up process was. Here is a table showing the currently available labels and their meanings.

Label name Label description
ADVNO EM advocate says event is not okay.
ADVOK EM advocate says event is okay.
ADVREQ EM advocate signoff requested.
cWB_r cWB_r
cWB_s cWB_s
DQOK Data quality information is available and does not veto the event.
DQV Data quality veto.
EMBRIGHT_READY EM Bright information is available.
EM_COINC Signifies that a coincidence was found between gravitational-wave candidates and External triggers.
EM_READY Has been processed by GDB Processor. Skymaps have been produced.
EM_Selected GraceID automatically chosen as the most promising candidate out of a set of entries thought to correspond to the same physical event.
EM_SENT Has been sent to MOU partners.
EM_Superseded GraceID automatically passed over because another entry was thought to be more promising and to correspond to the same physical event.
EM_Throttled GraceID is ignored by automatic processing because the corresponding pipeline submitted too many events too quickly.
GCN_PRELIM_SENT A preliminary GCN has been sent.
GRB_OFFLINE Indicates that offline triggered GRB searches found something coincident with this event.
GRB_ONLINE Indicates that online triggered GRB searches found something coincident with this event.

Protected labels

A few labels are “protected”; i.e., they are only applied by GraceDB itself as part of another process. These labels cannot be applied manually by users and any requests to do so will be rejected by the server.

At present, the following labels are protected as a part of the signoff infrastructure and are only applied by GraceDB after an operator or advocate signoff:

  • H1OK, L1OK, V1OK, ADVOK
  • H1NO, L1NO, V1NO, ADVNO
