It was recently proposed that the globular cluster system of the very low surface-brightness galaxy NGC1052-DF2 is dynamically very cold , leading to the conclusion that this dwarf galaxy has little or no dark matter .
Here , we show that a robust statistical measure of the velocity dispersion of the tracer globular clusters implies a mundane velocity dispersion and a poorly constrained mass-to-light ratio .
Models that include the possibility that some of the tracers are field contaminants do not yield a more constraining inference .
We derive only a weak constraint on the mass-to-light ratio of the system within the half-light radius ( M / L _ { V } < 6.7 at the 90-percent confidence level ) or within the radius of the furthest tracer ( M / L _ { V } < 8.1 at the 90-percent confidence level ) .
This limit may imply a mass-to-light ratio on the low end for a dwarf galaxy but many Local Group dwarf galaxies fall well within this contraint .
With this study , we emphasize the need to reliably account for measurement uncertainties and to stay as close as possible to the data when determining dynamical masses from very small data sets of tracers .
