These data are discussed in Ghazaryan et al. 2018

column 1: "Star_id" (same as column 1 of Table_CPstarsList.pdf)

column 2 to 5 : data for H, these columns are generally empty.

column 6 (F): _He [2] abundance of He[atomic number] with respect to the Sun.

column 7 (G): the error (+/- this value) of the abundance as published in the reference give in the next column. The reference list is the file References_numbered.pdf

column 8 (H): the reference number corresponding to the value of the two previous columns.
