The India-based Neutrino Observatory (INO) is a proposed underground facility located in India that will primarily house the magnetised Iron CALorimeter (ICAL) detector to study atmospheric neutrinos produced by interactions of cosmic rays with Earth's atmosphere. The physics goal is to to make precision measurements of the neutrino mixing and oscillation parameters through such a study. We present here the results from detailed simulations studies, as well as a status report on the project. In particular, we highlight the sensitivity of ICAL to the open issue of the neutrino mass ordering, which can be determined {\it independent of the CP phase} at ICAL.

Anonymous Report 1 on 2022-10-15 (Invited Report)


- Beginning on page 4, clarify if the MO sensitivity plot (fig. 2) does include hadron information.
- Fig. 3 could use a more detailed caption. Is it showing sensitivity to delta-CP for 10 years?
- Fig. 4 it's not clear what the different lines "with pulls", "with pulls and marginalization" indicate.
- Sec. 3 would benefit from showing an event display and/or event distributions from the simulation studies.
- What is the energy sensitivity expected? tau detection has a threshold of ~2GeV. Is ICAL expecting to be able to classify taus event by event?
- In the conclusion, "pending litigation" sounds ominous... perhaps can soften a bit.

Minor corrections
- "aout 2 eV" --> "about"
- "INO grauate" --> "graduate"
- "interact with mainly " --> "mainly interact with"
