The {cflx n} texture formed in a 2 mm diameter cylinder of superfluid {sup 3}He-B has been studied by continuous wave NMR near {Tc}. The experiments were performed at low pressures (0.82 and 2.89 bar) and using an axial magnetic field of 286 G to preserve the cylindrical symmetry of the texture. A method of deconvolution of the NMR lineshapes is presented along with the texture map obtained from the data. The texture resembled the calculated flare-out texture although differing in details including the existence of an azimuthal component to {cflx n}(r). By comparison to the Ginzburg-Landau expressions expected to hold near {Tc}, the magnetic bending length of R{sub C}H{sub B} = 37(1 {minus} T/{Tc}){sup 1/2} cm G was found, verifying the Ginzburg-Landau prediction.
