OBJECTIVE FUNCTION SCALING FACTORS

The methods may include selecting the scaling factors. Selecting the scaling factors may include selecting the scaling factors from a set of scaling factors. “Scaling factors” may also be referred to as “coefficients.”

The method of claim 51 or 52 wherein selecting the scaling factors comprises selecting from a set of scaling factors that comprises, for each of one or more aqueous solution conditions (i) a fluctuation scaling factor, (ii) an aspartic acid residue surface area scaling factor; and (iii) a main-chain nitrogen atom surface area scaling factor.
Помогите, пожалуйста, разобраться, как перевести "scaling factor" в данном контексте

Спасибо заранее!
