Abstract

The VOLKS pipeline is designed to carry out single pulse search and localization in VLBI data. Unlike the radio imaging based pipeline, in VOLKS, the search and localization are two independent steps. The search step takes the idea of geodetic and astrometric VLBI post processing, which fully uses the cross spectrum fringe phase information to maximize the single power. Compared with auto spectrum based method, it is able to extract single pulses from highly RFI contaminated data. The localization now supports both radio imaging and geodetic solving methods. The accuracy of geodetic method is comparable with that of radio imaging, but is much more efficient.
