SHARK-NIR Commissioning Activities List

This is an evolving page and the lists and activities will evolve in time as we gain more and more experience.

Although it is mentioned as the commissioning activities list, it lists all the activities of SHARK-NIR from its unpacking at LBT till the Science Verification, with the exception of the instrument installation at the LBT Bent Gregogian Central focal station.

The commissioning is broadly divided into 3 Phases:

Phase 1: We start from inspecting the boxes at LBT mountain bay, unpacking and installing the instrument at the mountain lab for alignment verification and functionality checks. All of these are daytime activities.

Phase 2: The activities after the installation of SHARK-NIR at the SX central bent Gregorian focus of LBT to the acquirement of the first nighttime telescope collimation model of the instrument form the Phase 2. Most of the activities are daytime. The only nighttime activity is to check the pointing, acquisition sequence and getting the first nighttime telescope collimation model for SHARK-NIR.

Phase 3: Phase 3 of the commissioning starts 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. By the end of this phase, SHARK-NIR is ready for Science Verification.
