Remove gstlal based online performance monitor
The online monitor added in gstlal_inspiral_postcohspiir_online
caused a crash when running with finalsink_need_online_perform
. That parameter is also used to log latency_history
in finalsink.
It'd require an upgrade for py3, but I believe we'll be using different online monitoring in O4 anyway. So I've removed it and related imports.
