Notes.Abundance uncertainties are estimated to be about ±0.2 dex for the magnetic Bp stars and ±0.1 dex for the non-magnetic normal and HgMn stars. Exceptional values are indicated in parentheses. The second to last column indicates the difference between the Si ii and Si iii abundances and the last column denotes the significance ΔSi / σD of the difference.
