Notes. First block, median parameters with a median 68% confidence interval for both sources A and B. Second block, best χ2 relative to the number of degrees of freedom. Third block, derived parameters including emission height, r, and transverse size of the emission region relative to the distance, r (semi-major and semi-minor axis of the approximating ellipse, a and b, respectively). Error bars apply do digits between parentheses.
