Update pile-up fractions for MC20
Update pile-up fractions for MC20.
The numbers are based upon a relative XS scaling of the high-pt slice of 64%, which leads to a relative high-pt / low-pt sampling of 0.001953314389 / 0.9980466856. Those numbers are then multiplied by 56.5 / 90.5 / 90.5 for MC20a / MC20d / MC20e. Only a relevant number of significant digits are kept.
Marking urgent as it is needed for the next round of validation.
