Early Integration Activities EIA Activities related to Auxiliary Telescope - 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 EIA Activities related to Main Camera address those issues - Exercises build on the work of previous ones - Test early, test often! - Reduces verification risk by doing early testing EIA Status Details – Physical & Functional Integration Breakout #lsst2018 LSST Project and Community Workshop 2018 • Tucson • August 13 - 17 7
Some Recently Completed Exercises - 1 Visit Night with Images AuxTel • First test of Auxiliary Telescope APIs • Ran through AuxTel nominal visit cadence - Manual Control of Multiple Physical Devices AuxTel First test of hardware control for monochromator • calibration - FITS File Assembly at NCSA • Test for correct image assembly for single CCD - MCM/OCS Bridge Integration Test • Control AuxTel Spectrograph sensor and Dewar to produce images • Tests ACCS, AT Header Service and AT Archiver #lsst2018 LSST Project and Community Workshop 2018 • Tucson • August 13 - 17 8

Commissioning Team working with DM on SW Tooling Automated scripted analysis through LSST Science - Tucson based weekly “Stack Club” + periodic Platform JupyterLab interface running at NCSA. “boot camps” with DM, T&S and Commissioning. Example is QA for galaxy identification. - B uilding 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 Interactive image analysis tooling #lsst2018 LSST Project and Community Workshop 2018 • Tucson • August 13 - 17 10
