H2O maser observations of W3OH using VERA
Abstract
We have started multi-epoch differential VLBI observations towards W3(OH) H2O maser source and a reference source J0244+6228 using VERA (VLBI Exploration of Radio Astrometry), which has a dual beam VLBI system. Some results of the observations will be shown. The H2O maser positions are basically consistent to the former ones indicating that the mapping capability of VERA is available for conventional mapping observations. The reference source J0244+6228 was also detected with good S/N ratio and point-like indicating this source is good for reference of differential VLBI. Our VERA system probably has a good performance for VLBI imaging.
