Notes.
Energies of levels for para-NH3 should be increased by 22 K if put on the common energy scale with ortho-NH3.
Counted from the reference maximum phase of the light curve, φ = 0 on Julian date JD = 2 454 554, and period of 630 days (Menten et al. 2012).
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
