    Joschua, The flat optics 5% beta-beating shift

    Identified to be the tune feedback that changed the telescopic MQTF.

    ################################

    Martin, Reanalysing Kmod form IP2 with more correct input

    A fix for the energy: Use current in the main bends (options: Timber, LSA?, read mains the same way as quadrupole). Same beta* 

    Ion emittance? flat? 

    Dispersion checked by Lukas, we have ~4cm error bar.

    Ana-> look at beta from amplitude

    Jaime -> Check correction, beta from phase (is good).

    Things to try:

    -Kmod in Q2

    -Measurement with flat orbit

    -Luminosity waist scan

    -Cogging + waist scan for the future

    Ewen: Sextupole correction is quite bad for beam 2, same as before correction ~1e-2.
