    2828== Introduction ==
    29 This commissioning planning document lays out and details the activities needed to bring SHARK-NIR online for __single-eye shared-risk scientific exploitation__ (the binocular observations with SHARK-VIS or trinocular with SHARK-VIS & LBTI are out of the scope of this commissioning plan). The document incorporates activities starting from the unpacking of the boxes at the LBT mountain bay to the early science (or 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.  Phases 1 and 2 are purely daytime activities. Phases 3 and 4 are nighttime activities. It is to be noted that Phase 3 activities are classified into observing cases (OC#, see the table below) and '''not''' according to the observing modes (direct imaging, coronagraphic imaging, long-slit spectroscopy) anymore. This allows commencing Phase 4 (science verification) of those observing cases immediately after the completion of the respective Phase 3 commissioning run. See below for more details.
    30 
    31  **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. This forms the content of the __PSR-09 Preliminary Laboratory Integration & Test (I&T) Procedure__ (at LBT). [Pre-commissioning: Unpack, assemble, and clean-room verification]
    32 
    33  **Phase 2**: The activities start 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]
    34 
    35  **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. The final form of the SHARK-NIR software, observing blocks, data-reduction pipeline, etc., will be tested for all the observing cases of the instrument. All the activities are at nighttime. However, some daytime activities may be anticipated as well. There will be a common run (Run 1) to test the basic common requirements for each of the observing cases. Run 2-5 blocks represent the nighttime technical commissioning of a set of 17 observing cases. After the completion of each of these runs, SHARK-NIR will be ready for Phase 4 (science verification) of the respective observing cases. [Commissioning]
    36 
    37  **Phase 4**: SHARK-NIR is ready for the final phase of the commissioning - the early science (or science verification) observations. The final performance of the SHARK-NIR will be analyzed using the data from this run. All the activities are at nighttime. By the end of this phase, SHARK-NIR is ready for single-eye shared-risk scientific exploitation. [Early Science or Science Verification]
