Hi, As you should be aware not calibrations has been done for the pp run at 14167 there were problem with the HV mainframes for the large BB ; This was later fixed, but such fixes can easily cause change in offset's (timing) so it it no surprise to see secondary bands. By the way the early BB cal in the pp also gives rise to a 'weak' second band.

There seems to be a problem with BB for the runs after 15469, I know it is not used for vertexing, but still the differnce is strange and I wonder if we know why is it like this?
