Confidence contours for intrinsic extinction AV and redshift z, assuming an SMC extinction law. Contours show the 68%, 95%, and 99.7% confidence regions. The favorite model corresponds to a high-redshift origin, consistent with an association with G3. The stars indicate the best fit values for G1 and G2.
