I measured OMC fringe wrapping after OFI replacement. First I ran the dtt template in 78942, which caused a lockloss. In the next try, I reduced the excitation from 3421 to 600, which corresponds to 2.4 um pp OMC L (H1:SUS-OMC_M1_DAMP_L_IN1_DQ). The attachment shows that OMC scatter is worse than one in April (blue: April vs purple: today). We may need to adjust the OFI temperature.
