    Notes:

    1. PV scan: /mnt/disks/4/7/data/ma008_PV_093-2145.vdif marked invalid by vdifuse
    2. PV: bad statistics before 092-2100 (OK after systems was restarted at Pico)
    3. PV: Autocorrelations show repeating strong features every 65 MHz. So far no fringes (PP-LCP.ps, PP-RCP.ps)
    4. YS: Autocorrelations show repeating strong features every 65 MHz. So far no fringes (larger clock-offset?) (YY-LCP.ps, YY-RCP.ps)
    5. MH: Autoccorelations look corrupted. Suspicous of 32 MHz sub-bands displayed as full band: So far no fringes, except for LCP (weak) in Scan No064. (MM-LCP.ps, )
    6. VLBA: subintNS has to be choosen to be 640000 when adding in VLBA (and EB) having 128 MHz wide subbands. If run with the default settings an erro concerning "data gaps" is received and no data is being correlated.
