The Science Data Model (SDM) schemas are a curated subset of the Rubin Observatory's database schemas, for its user-facing data products. They cover the data releases and previews, Data Release Processing, the Alert Production and Prompt Products databases, the Consolidated Database of Image Metadata, and other observatory metadata. Each schema is made up of tables, which contain columns along with keys, indexes and other database objects.

Schemas

ap_extra Additional tables that are produced daily but are not in the Prompt Products Database. 1
ApdbSchema 10.0.0 The Alert Production Database (APDB) contains the catalogs resulting from image differencing during nightly Prompt Processing as well as the results of daily Solar System Processing. 12
cdb_latiss 3.7.1 The Consolidated Database for LATISS schema contains information for each exposure and visit taken by the instrument, an imaging slitless spectrometer mounted on the Rubin Observatory Auxiliary Telescope. This includes observatory data from the FITS image header metadata and measurements and metrics from Rapid Analysis and other data processing. 13
cdb_lsstcam 1.9.1 The Consolidated Database for LSSTCam schema contains information for each exposure and visit (and each detector within those) taken by the instrument, the primary instrument for the Legacy Survey of Space and Time.

Rubin Observatory. This includes observatory data from the FITS image header metadata and measurements and metrics from Rapid Analysis and other data processing. 13
cdb_lsstcomcamsim 3.5.1 The Consolidated Database for LSSTComCamSim schema contains information for each exposure and visit (and each detector within those) taken by the simulated instrument. This information was recorded during an Operations Rehearsal. This includes simulated observatory data from the FITS image header metadata and measurements and metrics from Rapid Analysis and other data processing. 13

cdb_startrackernarrow 1.0.2 The Consolidated Database for StarTrackerNarrow schema contains information for each exposure taken by the instrument, a narrow-field star tracker mounted on the Simonyi Survey Telescope. This includes observatory data from the FITS image header metadata and measurements and metrics from Rapid Analysis and other data processing. 4
cdb_startrackerwide 1.0.2 The Consolidated Database for StarTrackerWide schema contains information for each exposure taken by the instrument, a wide-field star tracker mounted on the Simonyi Survey Telescope. This includes observatory data from the FITS image header metadata and measurements and metrics from Rapid Analysis and other data processing. 4
dp02_dc2_catalogs Data Preview 0.2 contains the image and catalog products of the Rubin Science Pipelines v23 processing of the DESC Data Challenge 2 simulation, which covered 300 square degrees of the wide-fast-deep LSST survey region over 5 years. 12
dp03_catalogs_10yr Data Preview 0.3 (ten-year version) contains the catalog products of a Solar System Science Collaboration simulation of the results of SSO analysis of the wide-fast-deep data from the full LSST ten-year dataset. 4
dp03_catalogs_1yr Data Preview 0.3 (one-year version) contains the catalog products of a Solar System Science Collaboration simulation of the results of SSO analysis of the wide-fast-deep data, based on analyzing only the first year of LSST observations. 4
dp1 1.3.1 Data Preview 1 contains image and catalog products from the Rubin Science Pipelines v29 processing of observations obtained with the LSST Commissioning Camera of seven ~1 square degree fields, over seven weeks in late 2024. 12
dp2 1.1.1 Data Preview 2 (Early) contains catalog products and coadded images from the Rubin Science Pipelines v30 processing of early observations obtained with LSSTCam from April 2025 to January 2026. Coadded images and catalogs cover ~3000 square degrees; single-epoch catalogs cover ~15,000 square degrees. 16
