remove fluence from cWB alerts for the start of O4
The issue of how and if to communicate fluence/hrss information for bursts public alerts was brought up over email and on the LL telecon of 20230405 ( https://wiki.ligo.org/Bursts/EMFollow/Telecon20230405 ). The consensus reached during the group telecon is not to communicate that for cWB (or any burst) alerts for the beginning of O4.
The immediate action required is to remove the corresponding lines in the VOEvent building code: https://git.ligo.org/computing/gracedb/server/-/blob/master/gracedb/annotations/voevent_utils.py#L597-634 .
At this moment, the EMfollow userguide requires no action as it correctly makes no mention of the fluence as a quantity that we distribute as part of the Burst public alerts. Likewise, there is no action currently needed by any of the burst pipelines.
The burst group should engage in deciding how and if the fluence/hrss information may become part of the burst public alerts in future updates of the O4 alert generation system.
