adaptive calibration can be achieved as follows: assumptions on the analytic properties of i lead to a measure of the consistency of the observations, from a given instant, with the total set of data; given an appropriate error model, an overdetermined system of equations in the unknown errors results; correcting the data accordingly, an improved estimate of i is derived; and the procedure may be repeated. this encompasses schemes proposed by readhead and wilkinson, and by cotton, for compensation of phase errors in very-long-baseline interferometry (vlbi); similar methods are proposed by muller and buffington for optical telescopes. results in analysis of very large array (vla) data are extremely encouraging. 19 refs
