Open tracking and alignment tasks
These tasks are part of the LS1
tasks list. If you interested in any of these tasks please contact Silvia Borghi, Michel De Cian and Patrick Koppenburg.
They are split in three depending if they are available, taken or completed.The completed tasks are still there because the analysis is made for 2011 and 2012 data. Anyway, further effort is needed for the post-LS1 data-taking, especially for documenting the analysis and organizing it into a package that could be run almost automatically for the next round of data-taking.

| Task name |
Review of HLT PV reconstruction |
| Task description |
The online and offline PV reconstructions differ in certain important respects, most notably in the fact that online PVs are made before a proper covariance matrix of the tracks is available. This leads to an incorrect covariance matrix for the PV and consequently to a loss of resolution in certain key selection variables such as the IPCHI2 of particles. In addition, the online and offline PV reconstructions often do not find the same number of PVs in multiple-PV events. The online PV reconstruction needs to be reviewed before 2015 and brought closer to the offline reconstruction wherever possible. |
