## VELO right half alignment
A significant drift (consistent with a rotation around the y-axis) was observed for the right VELO half during 2022 data-taking. To account for this, a dedicated right half alignment is required per run. The list of runs where this half alignment was evaluated can be found [here](https://gitlab.cern.ch/lhcb-conddb/lhcb-conditions-database/-/tree/alignment2022/Conditions/VP/Alignment/Global.yml). Please note that depending on the tag some runs might not have a dedicated half alignment.
