High-level Summary
Community Interactions, Meetings and Workshops
DM Scientist gave a PST Science Collaboration Chairs talk on the Rubin Science Platform
Members of the DM Science team met with the ANTARES team to discuss a proposal to deliver the Alert
Filtering Service with ANTARES
Though operations, several team members attended and presented at the third data facilities workshop
April 5-7.
The Network Engineering Taskforce (NET) Annual Meeting took place on April 21-22, 2022, from 11
am to 3pm following the SA3CC Spring meeting. The NET was by invitation only focused on objectives
of continuing the planning, development, and deployment of the LHN.

Technical Progress
DMTN-227 was drafted describing the Consolidated Database for image (and potentially other dataset)
The first phase in replacing Execution Butler with a graph-backed registry was completed. This will allow
batch processing to run without accessing any SQL-based registry.
The Alert Production team made major progress in improving the performance of the Heliolinc orbit
linking algorithm and fixing a noted completeness shortfall.
The Solar System Processing team of AP finalized the catalog of known objects and simulated new
detections for testing the data exchange with the Minor Planet Center.
Pipelines release 23.0.1 was made. It includes a number of tickets which were backported to support the
preops’ Data Preview 0.2 Data Release (DP0.2) coadd-processing (Tasks within the Pipeline subset
step3). PIFF (PSFs In the Full FOV) is now the default PSF modeling algorithm in the science pipelines.
The simplified imager readout (DMTN-143) compliant OODS has been deployed at the summit, enabling
us to remove the forwarder and archiver.
Transition of accounts and data from NCSA to SLAC have begun in earnest. Active NCSA login
accounts have been provided. NCSA admins are advising strategies based on what they’re seeing during
the start of the data transfer.
Improvements in our data services deployment infrastructure have greatly simplified the process for
testing upcoming service updates.
