so we just force this all the time, not just for some runs that are buggy?

Well, for all other runs this is done by the default auto mode anyhow ...

Actually, the best would be to fix the buggy CCDB objects, but this will be quite some work and the benefit will be minimal, since anyhow the common mode in pp 500kHz is very small. So the effect on the data which was not corrected in the electronics should be negligible.

I have a doubt about this. If we set the parameter here, do you think that other (good) runs will overwrite or ignore this parameter here? (I think that manually set things will have the highest priority).

Also to my understanding manually set values should have the highest priority. So this should (hopefully) overwrite everything that comes from the CCDB. The CM was enabled mid of 2023, so all runs after this will automatically switch to DigiMode=2. Now we force this to be done also for run before that date. This was anyhow also the default in older MC productions, before we changed to auto mode.

Did someone test that it actually works and fixes our problems? Then I can merge.
