Notes. Column (1) contains the Galactic coordinates; Col. (2) gives the distance from the Sun to the HII region; Col. (3) lists the sky brightness temperature derived from the measured intensity at the observing frequency; Col. (4) indicates the synchrotron brightness temperature of the column in front of the HII region (first 9 entries), and the synchrotron brightness temperature of the column behind the HII region (entries 10 and onward); Col. (5) gives the electron temperature of the HII region; Col. (6) gives the emissivity of the column in front of the HII regions (first 9 entries) and behind the HII region (entries 10 and onward); and Col. (7) indicates the origin paper of the data, where [1] is Jones & Finlay (1974), [2] Roger et al. (1999), [3] Nord et al. (2006), [4] Hindson et al. (2016), and [5] Su et al. (2016). (1) Electron temperatures updated with values from Azcárate et al. (1990). (2) Observed values not given in original paper; values calculated in P19. (3)Uncertainty absent in paper, we adopt 1.0 × 103 K.

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.
