Status of the observations

In the VLBA project BD215 we have targeted 21 binary systems. The observations are divided in 15 scheduling blocks (named with alphabetic names from A to O). Each of the SBs will be repeated six times, and the separation of the observations is choosen accordingly to the expected period of each independent system. The status at April 15 2019, is that a total of 54 epochs have been observed. The full calibration, data edition, and final images have been obtained for 49 (91%) epochs.

In Table 1, the status of each SB epoch is shown. We have labed the cells accordingly to the progress: Observed (O), downloaded (D), calibrated (C), and imaged (I). In the last column of this table it is shown the separation between two continuos runs of the SBs.
