LDM 612 makes it clear that individual science users will not be able to directly access the full LSST transient alert stream (there is limited bandwidth, so a small number of users will be able to directly access up to roughly 20 full-sized alerts per visit per filter), and that access to LSST alerts will be primarily facilitated by the community brokers.
If a US-based individual science user is interested in subscribing to the full LSST alert stream, which of the seven full-stream brokers (Alerce, AMPEL, ANTARES, Babamul, Fink, Lasair, Pitt-Google) are best-equipped to facilitate such access?
