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.
Note that the corresponding evolving doc in SHARK-NIR Dropbox folder is SHARK-NIR Commissioning Plan with document number SHARK-NIR-INAFP-COM-001.

Additional Information
Note:
- as of now, there is no one to one correspondence with the evolving doc (eventually they will be the same)
- you may see that there is some repetition in the activities. this needs to be sorted out eventually.
- the order of the activities may also be changed later.
To be added:
- Nighttime performance activities:
- Evaluate the seeing performance and Strehl achieved from the LBTI AO in closed-loop and in various seeing conditions.
- Look-up table activities:
- NCPA measurement for different telescope elevations?
Reminders:
- The space requirements at the mountain bay (@LBT) should be communicated to LBT at the earliest, along with the availability of crane operator, container moving tools, etc. Depending upon the month of the year, the mountain bay can be seriously booked (especially during July-October months due to summer shutdown).
- The same is true for the clean room near the mountain bay. If we need access to the LBTO network in the clean room, there are some network ports. But we may need to tell them in advance (Talk to Florian Briegel for more info).
- Note that if there is any ASM repair/activity scheduled in the clean room, preference is always for them and we will have to co-live or get after that.
- From the LINC-NIRVANA commissioning experience, it is always better to keep the tools associated with a particular alignment together, to avoid looking for it in all the boxes there. Also, there MUST be a living inventory wiki page where everyone should note down what is taken and kept in the box/container.
