1. What have the authors contributed in "C: " ?
The authors present new constraints on the density profiles of dark matter ( DM ) halos in seven nearby dwarf galaxies from measurements of their integrated stellar light and gas kinematics.. The authors present a data set of high-resolution integral-field spectroscopy on seven galaxies and measure the stellar and gas kinematics simultaneously.. Using Jeans modeling on their full sample, the authors examine whether gas kinematics in general produce shallower density profiles than are derived from the stars.. While such models do not yet have falsifiable predictions that the authors can measure, they investigate correlations that may eventually be used to test models.. The gas kinematics of low-mass galaxies frequently suggest that they contain constant density DM cores, while N-body simulations instead predict a cuspy profile.. Determining the importance of these correlations will require further model developments and larger observational samples.

2. What are the future works in "C: " ?
The authors have searched for correlations to explicate such a mechanism, and none are yet promising as directions for further research.

3. What software packages were used to create the final image?
The three related software packages of SExtractor (Bertin & Arnouts 1996), SCAMP, and SWarp (Bertin et al. 2002) were used to create the final image.

4. How many bins did the authors need to get to the minimum?
In order to reach a minimum S/N = 10 per pixel, which is their desired threshold for kinematic extraction, the authors had to bin the galaxies into roughly 10 bins per galaxy.
