Results of different types of calculations in SFDM for NGC 2403. The simple calculation is the approximation described in Appendix C.2.1. The full calculation is the fully axisymmetric SFDM calculation. The full+nocurl calculation uses the same as the full calculation but uses a no-curl approximation for the phonon acceleration, a_θ. This is for the best-fit parameters obtained in Appendix D.2. Left: Rotation curve for the different types of calculations (lines) and the observed rotation curve from the SPARC data (circles with error bars). Right: Field for the same types of calculations, except for full+nocurl, which has the same as the full calculation.
