Comments on "Modeling Galaxy Halos Using Dark Matter with Pressure"
  We comment on the calculational mistake in the paper "Modeling galaxy halos
using dark matter with pressure" by Somnath Bharadwaj and Sayan Kar. The
authors made a mistake while calculating the metric, which led to an
overestimate of the deflection angle of light passing through the halos for
-1<w_r<-0.5 and an underestimate of the deflection angle for -0.5<w_r<0. In
addition, solution for w_r>0 should not exist. Although the Bharadwaj-Kar
solution should be corrected, it appears that the characteristics of the
deflection angle under the supposed non-conventional non-ideal fluid equation
of state for the dark matter halo remain sensitive to the impact parameter and
may be verifiable through observations.
