In our analysis we take the variable (Formula presented) instead of x in front of the bracket in the last sum on Eq. (22). The fit (Formula presented) value) agrees with the fit based on Eq. (22) at the percent level. At the same time the value of (Formula presented) around thresholds is shifted by up to (Formula presented) also changing the form of the positivity constraint leads to changes of (Formula presented) in this region of similar size. Other subtraction terms and positivity constraints are under study and will be presented in a future publication

We introduce below (Formula presented) and (Formula presented) to describe densities of c- and b-quarks, respectively, like in any standard massless scheme with 5 flavours. Note also that formally, at the moment, we have all five densities at each (Formula presented) These “initial” densities for c- and b-quarks are later modified according to the ACOT prescription, leading to the final densities denoted by the same symbols; see main text for a detailed explanation
