Alert Broker workshop

Leanne Guy

The community are organizing a workshop on alert brokers :  LSST Enabling Science 2020 broker workshop . This workshop will be the first of two workshops about brokers and their community of users. Several of you will have received a mail from Francisco Forster inviting DM to give a presentation at this workshop. 

Eric Bellm has replied to Francisco confirming that LSST DM will give a presentation. Eric will give the presentation (possibly pre-recorded) Melissa Graham Leanne Guy will help Eric to put together a presentation on the requested topics and will make available for input. 


Image Differencing: ID DMS-REQ-0032

3.2.3 Image Differencing: ID DMS-REQ-0032 (Priority: 1b)

Specification: The DMS shall provide software to perform image differencing, generating Difference Exposures from the comparison of single exposures and/or coadded images.

Associated Test Case: LVV-T126 

  • It is ambiguous whether this  requires calexp-calexp diffs in addition to the more standard calexp-coadd diffs.
  • If we interpret it that way, then there is the issue that, Gen 3 doesn’t allow us to do calexp-calexp subtractions.


  • Single-epoch-depth coadd: is a regular coadd made from a single visit, or a suite of visits that don't actually overlap (or barely overlap) - but unlike the original single-visit image, still resampled to the kind of coordinate system we use for other coadds.
  • Pairwise processing in CPP in Gen3
