Note that the most probable values and the 68% confidence interval are taken from a bootstrap fit, illustrated in the plots below. The reference position is shown has been corrected based on the position of the primary phase reference calibrator in the rfc2019a catalog. The displayed uncertainty is dominated by the uncertainty in the position of the in-beam calibrator employed. For each coordinate axis, this is estimated as the quadrature sum of 1) the uncertainty of the phase reference source in rfc2019a in this axis, 2) a value of 0.8 mas, which is the median core-shift between X band and L band (see the PSRPI paper for more details), and 3) the estimated phase referencing uncertainty from the phase reference source to the in-beam calibrator (estimated using the scatter in the positions obtained without self-calibration across all epochs). This estimate of absolute position uncertainty should be used with caution.
