Notes
- Data format VLBA: INTERLACEDVDIF/0:1:2:3:4:5:6:7/5032/2
- Data format Pv, Ef, On: DBBC2-astro
- Data format Ys, Mh: DBBC2-astro2
- Data format P3: BBC1-U,BBC1-L,BBC2-U,BBC2-L,....
- P3: Fringe SNR generally lower than with Pv-DBBC2. Autocorrelation bandshape suspect (DBBC2 reference, vs. DBBC3). Needs to be investigated
- The scan with DBBC3 has 299.796 s of data while the DBBC2 scan has only 296.645 s. This may explain a few minor discrepancies. I suggest to FF with cutting at the end and beginning of the scan so that we will have exactly the same data for both.
