Was this already tested with an appropriate MC-job?

Was this already tested with an appropriate MC-job?

Could you clarify what you mean by an appropriate MC-job?

I tested it locally by temporarily renaming --tpc-mc-time-gain to --tpc-mc-time-gain-TEST (so that reconstruction would not know this option). I ran it both with and without passing the remapping parameters (using a script like the one below), and in both cases it behaved as intended.
