Previously, we pointed out the possible advantages of inhomogeneous magnetic sector fields for mass spectrometers, as these fields permit a substantial increase in mass dispersion and resolving power without change in radius or slit widths. In the said paper we calculated the coefficients of the second order aberrations in the median plane, as well as the field shape required to eliminate the second order angular aberration in the median plane. In the present paper we calculate the second order aberrations outside the median plane referring to focusing in the radial direction. Moreover, the influence of fringing fields is being neglected, and the field boundaries are supposed to be plane and normal to the main path at the point where it enters and leaves the field.
