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. This is due to phase jumps between the subbands which can be corrected by applying manual phasecal. If applied DBBC2 and DBBC3 fringe SNR is comparable.
- P3: There is a drop in amplitude on BBCs 5-8 compared to BBC 1-4 in LCP (only visible in the plots containing all 16x32channels). This needs to be checked during the next test observations. A possible explanation would be that AGC was accidentally disabled for those BBCs.
- Data weights for VLBA stations < 1.000
