SHARK-NIR Commissioning Plan
Table of Contents
This commissioning planning document lays out and details the activities needed to bring SHARK-NIR online for regular scientific exploitation. The document incorporates activities starting from the unpacking of the boxes at the LBT mountain bay to the early science /science verification at its final destination on the LBT platform. Although called the commissioning document, it lists the pre-commissioning, commissioning, and science verification activities.
The activities are classified into four phases:
Phase 1: We start by inspecting the boxes at LBT mountain bay, unpacking, and installing the instrument at the mountain lab (clean room) for alignment verification and functionality checks. All of these are daytime activities. [Pre-commissioning: Unpack, assemble, and clean-room verification]. This forms the content of the PSR-09 Preliminary Laboratory Integration & Test (I&T) Procedure (at LBT).
Phase 2: The activities starting from the installation of SHARK-NIR at the SX central bent Gregorian focus of LBT, followed by preliminary functional checks, aligning SHARK-NIR to the telescope (daytime), and daytime closed dome engineering/technical testing. All of these are daytime activities. [Pre-commissioning: Installation, functional checks, and closed-dome testing]
Phase 3: Phase 3 commences the nighttime commissioning, starting from sending preset to the telescope to testing individual SHARK-NIR observation modes for performance to the total SHARK-NIR performance. All the activities are nighttime. However, some daytime activities may be anticipated as well. By the end of this phase, SHARK-NIR is ready for early science observations. [Commissioning]
Phase 4: SHARK-NIR is ready for the final phase of the commissioning - the science verification / early science observations. The final form of the SHARK-NIR software, observing blocks, data-reduction pipeline, etc., will be tested for all the modes (and sub-modes) of the instrument. The final performance of the SHARK-NIR will be analyzed using the data from this run. All the activities are nighttime. By the end of this phase, SHARK-NIR is ready for regular science operations (with some 'risk,' of course, for another year). [Science Verification / Early Science]

Naming structure of the commissioning activity
Each commissioning test/activity has a unified structure as follows:
Name of the commissioning activity - phase : states the phase of the commissioning (1/2/3/4) - status : reports the current status of the test (draft, final, complete) - category : one of the categories mentioned above - recurrence : describes how frequently the test must be executed - duration: estimates the time required to complete the test (the duration mentioned here is valid only for commissioning) Description - Contains a general description of the test Prerequisites - Lists items that must be in place before the test begins Procedure - Explains in detail how to execute the test Success Criteria - Enumerates the outcome associates with successful completion of the test Notes - Additional supporting information LBTO Support - Mention if (and what) support required from LBTO Associated SHARK-NIR personnel - Mentions here who are the associated personnel to the test Date performed and by whom - Mentions who performed the test and when
Commissioning Activity
