MCH: add cut random fraction setting for the cases with and without ITS #14028
Conversation
Two new environment variables are introduced to provide the fraction of rejected MCH events separately for the cases where ITS is either included (CUT_RANDOM_FRACTION_MCH_WITH_ITS) or excluded (CUT_RANDOM_FRACTION_MCH_NO_ITS) from the data taking. The CUT_RANDOM_FRACTION_MCH variable, as well as the two new ones, can still be overridden by setting them explicitly in the shell environment, therefore the changes are backward compatible.

this seems wrong, I assume you want to check if the _ITS variable is not empty?

Actually not... I want to set CUT_RANDOM_FRACTION_MCH from CUT_RANDOM_FRACTION_MCH_WITH_ITS only if CUT_RANDOM_FRACTION_MCH is not set already.
In other words, I want to be still able to set something like CUT_RANDOM_FRACTION_MCH=0.5 in the extra ENV variables to completely override the defaults.
Does it make sense?

ok, fine with me.
But please check in both assignments that CUT_RANDOM_FRACTION_MCH_WITH_ITS or CUT_RANDOM_FRACTION_MCH_NO_ITS respectively are set. So we don't access an undefined variable accidentally.

@davidrohr sorry, I missed your comment... doesn't the :- construct in the variables access guarantee that a default empty value is used if the variable is not defined?

This PR did not have any update in the last 30 days. Is it still needed? Unless further action in will be closed in 5 days. |
