    #####

    GetLLM status, Lukas

    GetLLM is now well modularized with good data common structures. Missing fixes: AC compesation (specially in coupling to be patchy), and debugging. Resynchronization to be passed to hole_in_one.

     

    ####

    MDs

    b3 in beam 1 || emit growth from octs in beam 2

    MCS switched off with coupling measurements for MCS feedown.

    MCS set to amplify b3 from dipoles -> AC dip and MKA meas

    DOROS parasitic acquisitions for BPM synchronization diagnostics (amplitude should be small, Beam2 probably never checked).

    BSRT 2D info logged by Ewen and Tobias for the beam 2 MD.

    #########

    Jaime and Leon, Offsets in quads from Kmod,

    Error bars added. 

     

    #########

    AC dipole sidebands

    Look for smaller kicks in the same day.

    Need to add file time info to hole-in-one.

    BFSOU, check other BBQ data without filtering.
