VLBI Observation of Pulsar B0329+54 with the CVN at S/X Bands ☆ ☆☆

A VLBI (Very Long Baseline Interferometer) observation of pulsar B0329+54 was carried out with the CVN (Chinese VLBI Network) in February 2015. It is the first time for the CVN to observe the pulsar B0329+54 in the S/X dual frequency bands. The observation was performed in the phase referencing mode. The observational data, including 16 channels of 16MHz bandwidth, were collected by the CDAS (Chinese Data Acquirement System). The correlation was made by the DiFX (Distributed FX) correlator at Shanghai Astronomical Observatory. The pulsar binning mode of DiFX was used to increase the signal to noise ratio of pulsar fringes. We obtained the accurate position of Pulsar B0329+54 from its VLBI image. Our result is in good agreement with the previous VLBI results.
