The second column indicates if $T_{\rm e}$ was computed using the direct method (D) or via empirical calibrations (EC) in this work. a We follow ITL97 names in SBS 1319+579. Notice, however, than IT99 named region A to SBS 1319+579 C and region B to SBS 1319+579 A; they did not consider SBS 1319+579 B because of its higher uncertainties. References: G97: Gallego et al.
