Abstract

The conclusion that the diffuse galaxy NGC1052-DF2 is deficient in dark matter depends critically on the distance, as noted in the original publication and subsequent works. The results of our preliminary assessment of the SBF distance have already been referenced on the web. Here we present the details of a more careful analysis, supply some context, and comment on the remaining uncertainty.

Comments

2 pages, accepted by Research Notes of the American Astronomical Society; text is a bit laconic because of the RNAAS word limit
