Calibrated squared visibility and closure phase measurements of several calibrator pairs observed during 2003 October 30–November 18, under identical observing configuration, in order to estimate calibration errors. The estimated calibration error in the squared visibility measurements is ~4% and, that of the closure phase measurements is ~0.8°.
