Rework handle_cbc_event to avoid the need for download retries
Modify the condition under which we calculate p_astro so that we
do not need to repeatedly try to download ranking_data.xml.gz.
We will be having an extended maintenance of https://git.ligo.org, https://containers.ligo.org, and https://docs.ligo.org on 7 May 2024 starting at approximately 9am PDT and lasting for three to four hours. This is to start the process of syncing the data from the current instance to the re-engineered instance we have been working with GitLab on over the past few months. Starting at approximately 9am GitLab will be put into maintenance mode, meaning that all services will be in read-only mode. Throughout the maintenance there may be several periods of downtime. Please address any comments, concerns or questions to the helpdesk.
