Many synthesis arrays currently in use have at least a few redundant baselines which can be used to derive model-independent telescope corrections. We discuss the relative merits of redundancy-based versus standard selfcalibration methods with respect to sensitivity to noise and interference. We then derive an approach to optimally combine the two methods for partially redundant arrays
