Table information for 'alerce_tap.lsst_forced_photometry'

General

Table Description:

LSST forced photometry measurements extracted at DIA object positions on individual visit images, including PSF flux and forced science flux with uncertainties, and temporal processing metadata.

This table is available for ADQL queries and through the TAP endpoint.

Resource Description:

Multi-survey astronomical object catalog containing astrometric and statistical information from multiple surveys. This table provides aggregated properties for astronomical objects including position, detection statistics, and temporal coverage.
