Basic Radio Astronomyoughly undesirable state of affairs because, in science, we demand that others can repeat experiments and come to the same conclusions. We must learn enough about our measuring systems to be able to make allowances for instrumental effects.

Sensitivitysignal are described. Then the sensitivity for fringe detection, which sets the limits on the weakest source that can be observed in most cases, and for the off-source noise in an image are given. Finally, some specific examples are presented.

An Introduction to Deconvolution in VLBI methods, . CLEAN and the Maximum Entropy Method (MEM), is outlined and their relative merits for VLBI imaging briefly discussed. The temptation explicitly to ‘super-resolve’ the image should be resisted.

Mapping in Practice mapping with the AIPS (Thompson and D’Addario, 1982)-package. Other data reduction systems do exist, e.g. the Caltech-package and OLAF. These differ from AIPS mostly in the . for reaching the final and “best” map. It is more important to know the method and to be careful than what reduction procedure is used.

Introduction to Phase-Reference Mapping and limited coherence time. The basic theory for source-switched observations is given. The necessary steps in a phase-reference mapping observation are described and the results of a switched phase-reference observation are shown as an example. A short discussion outlines the major difficulties of the technique.
