High-level Summary

Community Interactions, Meetings and Workshops

DM Scientist supported the project AOS (Active optics System) workshop and was interviewed by on Rubin/LSST

Jeff Carlin Support commissioning observing activities in Chile

DM produced all of the content for the Commissioning Science Validation Bootcamp which consisted of live tutorials as well as pair coding sessions with new commissioning in-kind contributors.

Technical Progress

Document DMTN-213 describing multi-site Data Release processing was published.

Technical work for Data Preview 0.3, which focuses on solar system objects, was completed and deployed on the main Rubin Science Platform and handed over to the Community Science team. Although this work was done under the Rubin Pre-Ops program, like the previous Data Preview releases, it demonstrates the maturity and operational readiness of the Construction systems and processes. After early community testing, a public announcement will be made in time for the Project and Community Workshop. DP0.3 also includes the first service in production that follows the USDF on-prem/cloud hybrid model: the Rubin Science Platform TAP service servicing data preview delegates on the Google-hosted accesses data in a database deployed at SLAC.

The first execution of the Prompt Processing pipeline was successfully completed using Auxiliary Telescope on-sky imaging following improvements to the Prompt Processing framework.

PipelineTask wrappers were written for the Solar System Processing (SSP) pipeline, allowing SSP to be run using Gen 3 middleware. The real-bogus Machine Learning model trained on simulated DC2 was successfully used to score the reliability of transients in HSC Cosmos data. Real-bogus reliability classification was added to the AP pipeline run nightly in Continuous Integration.

Newly available in the Rubin Science Pipelines is a preliminary Task to build a multiband Chi2 coadd that implements Szalay+99. It will be turned on by default for deep detection after science validation confirms that it performs better than the union of detection on single-band deep Coadds.

The Base Test Stand cluster in our facility at La Serena was delivered by our IT team for software testing. It is our first cluster based on Enterprise Linux 8.

DM completed work as part of the Cycle 30 summit system upgrade, including updates to the Header Service and the Observatory Operations Data Service.
