Notes. Exponents are given in parentheses, e.g., 1.4(16) = 1.4 × 1016. The errors of the continuum parameters are indicated by subscript (left) and superscript (right) values, e.g., 
is the lower limit of 1.0 × 10+25 − 4.7 × 10+00 and 1.0 × 10+25 + 3.0 × 10+00 is the upper limit of the corresponding hydrogen column density of 1.0 × 10+25. For sources marked with an asterisk (*), we could not derive a self-consistent description of the continuum of the corresponding core spectrum. Here Tdust indicates the dust temperature in K, NH,dust the hydrogen column density in cm−2, and βdust the power-law index of the dust emissivity. We use temperature units for the fitting. Therefore, the spectral indices for flux units α is given by α = β + 2. Additionally, γdust describes the contribution of dust to the total continuum of the corresponding core spectrum in %, Te the electron temperature in K, EM the emission measure in pc cm−6, and γff the free-free contribution to the total continuum in %.
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.
