High-level Summary

Community Interactions, Meetings and Workshops

DM Scientist submitted a Rubin proposal for a single-band Roman survey covering the LSST Wide-Fast-Deep footprint to the Roman Space Telescope’s call for Core Community Surveys, together with other PST members.

Technical Progress

The DM-SST reviewed the status of cell-based coadds and processing algorithms for weak lensing from the DESC. The metadetect algorithm will be adopted by DM for producing per-object shear estimates. A conceptual schema to add to the DPDD has been proposed.

In Science Pipelines, the default PSF model, PIFF (PSFs in the Full FOV), can now fit PSFs in sky coordinates. The capability to fit in sky coordinates is especially important if the detectors have small-scale WCS distortions (for example DES’s deep treerings). Also added a new mode to image differencing, to support preconvolution of the science image and use of the maximum likelihood image for diaSource detection.

We fully set up and redeployed the Alert Distribution prototype on the IDF.

The NCSA data hosted at Fermi has largely been transferred to SLAC/USDF, and an audit is taking place to make sure everything has been transferred. Testing of HTCondor over Slurm continues; we are currently concentrating on memory scaling.

Concluding a major package of work, the RSP Identity and Group Management system based on CILogon/CoManage deployed to production on Current users transitioned with help of the CST team. In other RSP new, Milestone LDM-503-RSPa declared met by the V&V team.

DMTN-249 on Butler redesign and DMTN-254 on the Summit architecture from the DM perspective were drafted. Designs for ingest of Large File Annex datasets, including those from the Guider, were documented.
