Rotation curve decompositions for NGC 891 and NGC 7814. Top panels: surface brightness profiles at 3.6   μm for the bulge and the stellar disks built from the parameters of Table 4 (for NGC 891 the two disks have been added). Middle panels: H I surface density. Bottom panels: best fit with an isothermal dark matter halo, the parameters of the fits are given in Table 5. 1   kpc = 21.7″ and 33.4″ for NGC 891 and NGC 7814 respectively.
