Abstract

Read article at ArXiv

The paper TDCOSMO XXVI: Uniform Lens Modeling of Eight Doubly Imaged Quasars by Brady et al. contained some errors which have been corrected in a revised version.

The authors identified a slight error in the coordinate framing used in the work, resulting in an improper reflection of the model coordinates about the declination axis.

Importantly, this does not affect any of the scientific results or conclusions of the paper. Rather, the coordinate transformation affects how a small number of quantities are reported. Specifically, the quoted position angles (PA) should be transformed as (180 degrees - PA), while the signs of the relative RA values reported in Table 4 should be flipped.

The updated version of the paper corrects the position angle values reported in Tables 2, 3, and 6, as well as Figures 8, 13, and 14, followed by correcting the signs of the relative RA values in Table 4.

These corrections have no impact on the validity of the results or the conclusions.

The overlay for the paper now links to the corrected manuscript; the earlier version can still be found on arXiv.
