  • Key activity of Phase 0: Pre-Commissioning
  • Involves interaction between all principal

subsystem control software

  • Mainly focused on software, but hardware

becoming involved

  • Performs interface testing
  • Designed to clarify and solidify those interfaces
  • Used to identify areas of deficiency and

address those issues

  • Exercises build on the work of previous ones
  • Test early, test often!
  • Reduces verification risk by doing early testing

Early Integration Activities

Commissioning Team working with DM on SW Tooling

  • Tucson based weekly “Stack Club” + periodic

“boot camps” with DM, T&S and Commissioning.

  • Building experience and expertise with data

analysis tools

  • Scripted data analysis tooling with LSST SW Stack
  • Interactive image analysis tooling
  • Deployment of early Camera DAQ-CCS instances

for cross-subsystem integration tests

Automated scripted analysis through LSST Science Platform JupyterLab interface running at NCSA. Example is QA for galaxy identification. Interactive image analysis tooling
