General:
- This experiment contains ALMA with 32x62.5MHz channels sampled at 125MHz.
- VLBA was recorded with 2x128MHz channels
- DBBC2 statons were recording 1x512MHz wide channel

- Mh weak fringes in LCP to Onsala at beginning. Auto-correlations indicate errors in
- No fringes to Pt
- VLBA Fringes were found using the 2x128MHz mode.

Frringes between ALMA and Eb (Effelsberg RDBE 2x128MHz):
Aa-Eb.pdf . SNR for Aa-Eb much lower than for Aa-Ef. Needs to be investigated
Notes:
- PV scan: /mnt/disks/4/7/data/ma008_PV_093-2145.vdif marked invalid by vdifuse
- PV: bad statistics before 092-2100 (OK after systems was restarted at Pico)
- PV: Autocorrelations show repeating strong features every 65 MHz. So far no fringes (PP-LCP.ps, PP-RCP.ps)
- YS: Autocorrelations show repeating strong features every 65 MHz. So far no fringes (larger clock-offset?) (YY-LCP.ps, YY-RCP.ps)
- 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 MM-RCP.ps)
- 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 WARNING concerning "data gaps" is received and no data is being correlated.
