Notes. The columns are defined as follows (from left to right): Col. 1: Object name; 2: Source ID (from K22); (3)-(4): Metallicity and effective temperatures as listed in K22 (see their Table 1); (5): Luminosity derived in the present study (see Sect. 2); (6): Luminosity from K22 (see their Table 1), obtained considering the upper and lower limits of the distances retrieved from Bailer-Jones et al. (2021); (7): C/O from K22 (see their Table 3); (8)–(10): Optical depth at 10 μm, dust temperature, and distance separating the central star from the inner border of the dusty region, found via SED fitting; (11): The quality flag (Q1 or Q2), based on the Gaia EDR3 RUWE parameter from K22. The last eight rows are the carbon stars in the sample of T22.

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.
