Notes.
Cross section, in units of the square of the Bohr radius a02, of the collisional broadening under the ABO theory (Anstee & O’Mara 1995).
Electronic configurations of the lower and upper levels the table values are taken from Borrero et al. (2014) but corrected for the typo of the electronic configuration of the lower level of the 6301 Å line.
