Notes. Effective-temperature estimates are from the silicon ionisation balance (Si) or the He ii profiles at 4541 and 4686 Å. The former used the microturbulent velocity estimates from the absolute silicon abundance (method 2). Microturbulence estimates are from the relative strengths of the Si iii triplet (1) or the absolute silicon abundance (2).
