THE GOALS OF THIS WORK FALL WITHIN THE SCOPE OF THE COSMIC ORIGINS PROGRAM BY ADDRESSING THE QUESTION "HOW DOES THE UNIVERSE WORK?" (2014 NASA SCIENCE PLAN P. 74). OUR WORK WILL PROVIDE FUNDAMENTAL DATA ON THE NATURE OF GALAXIES. IT WILL EMPOWER OTHER SCIENTISTS TO DETERMINE STELLAR MASSES WHERE NECESSARY FOR THEIR WORK; FOR EXAMPLE IN CALIBRATING THE RELATION BETWEEN STELLAR MASS AND DARK MATTER HALO MASS. GIVEN THE STRONG RELATIONS WE OBSERVED BETWEEN BARYONS AND KINEMATICS THIS WORK WILL ALSO PROVIDE ASTROPHYSICAL CONSTRAINTS ON THE NATURE OF DARK MATTER AND THEORIES OF GALAXY FORMATION.
