Notes. The entire table is available at the CDS.

(a)

Upper and lower JK quantum numbers.

(b)

Predicted frequency (in MHz).

(c)

Uncertainty in the predicted frequency (in MHz).

(d)

Energy (in K) of the upper energy level of the transition.

(e)

Einstein coefficient of the transition (in s−1).

(f)

Line strength.

(g)

Degeneracy of the upper level. It is 2J+1 for all levels except for those with K = 3  ×  n (n = 1,2,…), for which gu is 2 × (2J+1).

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.

Initial download of the metrics may take a while.
