Calibrator models used for VLBA astrometry of XTE J1810-197

J1753-1843 and J1819-2036 are phase calibrators used for the VLBI (very long baseline interferometry) astrometry of XTE J1810-197, the first magnetar that was found to have emitted radio pulses. Calibrator models are essentials for repeating our astrometry. They would also be useful if other astronomers wanted to further the VLBI astrometry based on the same calibrator setup. The two images were made from the respective data concatenated across all available epochs, which were subsequently adopted as the calibrator models for all epochs.
