Version: 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.

Tables

name	description	columns
Object	Descriptions of static astronomical objects (or the static aspects of variable and slowly-moving objects) detected and measured on coadds.	1296
Source	Properties of detections on the single-epoch visit images, performed independently of the Object detections on coadded images.	156
ForcedSource	Forced-photometry measurements on individual single-epoch visit images and difference images, based on and linked to the entries in the Object table. Point-source PSF photometry is performed, based on coordinates from a reference band chosen for each Object and reported in the Object.refBand column.	28
DiaSource	Properties of transient-object detections on the single-epoch difference images.	87
DiaObject	Properties of time-varying astronomical objects based on association of data from one or more spatially-related DiaSource detections on individual single-epoch difference images.	137
ForcedSourceOnDiaObject	Point-source forced-photometry measurements on individual single-epoch visit images and difference images, based on and linked to the entries in the DiaObject table.	28
CoaddPatches	Static information about the subset of tracts and patches from the standard LSST skymap that apply to coadds in these catalogs	5
Visit	Metadata about the pointings of the telescope, largely associated with the boresight of the LSSTComCam focal plane as a whole.	15
CcdVisit	Metadata about the nine individual CCD images for each Visit in the DP1 LSSTComCam dataset.	50
SSObject	LSST-computed per-object quantities. 1:1 relationship with MPCORB.	3
SSSource	LSST-computed per-source quantities. 1:1 relationship with DiaSource.	23
MPCORB	Orbit catalog produced by the Minor Planet Center based on submissions from DP1 processing. The columns are described at https://minorplanetcenter.net//iau/info/MPOrbitFormat.html .	10
