I generated few more files:

- job.ti2lhc.aperture_lhc.madx -> aperture computation for the LHC part

- job.ti2lhc.aperture_ti2.madx -> aperture computation for the TI2 part

- job.ti2lhc.optics.madx -> optics computations for the combined TI2/LHC transfer line You will notice that: - the monitors have the right name.

There is a BTVSI at the entrance of the kickers, is there another element? - the aperture computation is performed for a round halo - the aperture model of the LHC is based on measured profiles - offset files are used (they are in my directory): we should verify that everything is in good order for the MSIs. The use of offset files requires to split computations for LSS and arcs: the TFS tables with n1 values will have to be combined afterwards, which is possible
