The Prompt Products Database (PPDB) stores the outputs of Prompt Processing. Both an input and an output of the Alert Production pipelines. Image differencing produces DIASources associated into DIAObjects and known SSObjects produce alerts (DIObject, DIASource history, DRP Objects…) (later) linked to find new SSObjects (later) trigger forced photometry Required to be accessible within L1PublicT = 24 hours of acquisition (DMS-REQ-0004) Must enable alert generation within OTT1=60 seconds. #lsst2018 LSST Project and Community Workshop 2018 • Tucson • August 13 - 17 2
