High-level Summary
Community Interactions, Meetings and Workshops
Though AAS was canceled, some sessions continued. There was a DM presentation at the
AAS 239 splinter on joint survey processing. DM supported the AMCR in January.
Technical Progress
Many notes were updated or released including:
● Issued DMTN-213 describing distributed Data Release Production.
● Issued DMTN-219 describing a proposed Prompt Processing design and prototype.
● A new version of DMTN-049, Roadmap to Photometric Redshifts for the LSST Object
Catalog, was released following receipt of letters of recommendation from the
● An abstract for the faro metric computation package was submitted to SPIE.
● Rubin-Euclid Derived Data Products – Initial Recommendations report released
The outputs of the Gen3 data release pipeline are scientifically equivalent to those of Gen2
pipelines. This means that all prerequisites for removing generation 2 middleware are now
complete. Gen3 middleware also allows per-pipelines configurations. This feature means
that we can now, for example, speed up AP by running fewer measurement plugins during
DRP single-frame processing.
Moneypenny, our nublado user provisioning service, has been refactored to improve its
performance. This reduces the perceived startup time for users.
All seven Rubin Community Brokers were able to successfully connect to the new Alert
Distribution Service, which is documented in detail in DMTN-210. The Solar System orbit
propagation code was re-written in C++ for a significant speed increase.
A more computationally efficient version of Scarlet is now available. Scarlet Lite is more
than 30% faster and more memory efficient with no degradation in robustness. This will become the default deblending algorithm in April.
NCSA is coordinating hardware from the NCSA test stand (NTS) to be shipped to Tucson or
Chile. The NTS will be shut down imminently.
Steve Pietrowicz is taking over as TCAM for Michelle Butler as she retires in April.
