On the data combining technique for multiple VLBI networks to increase image fidelity

Abstract

The attainment of high-fidelity images obtained with Very Long Baseline Techniques and earth-rotation synthesis is the main observational quest to study the physical properties of cosmic radio sources for various astrophysical and cosmological purposes. In this paper, I present a method to combine individual array observations in radio continuum mode at 4995 GHz which is successful when obtaining enhanced images of radio sources. The data combining techniques explained here allow to produce synthesis array images which show details which cannot be obtained by standard data processing and observational techniques with individual arrays.
