Abstract
Measurements of average pulse profiles made with a single linear polarization over the range 41-112 MHz are presented for PSR B0950+08. We show that the observed variable structure of the pulse profiles is a result of Faraday sinusoidal modulation of the pulse intensity with frequency. The rotation measure corresponding to this effect, $RM \approx 4\ {{\rm rad\, m^}}$ , is about 3 times greater than the published value of $RM = 1.35\ {{\rm rad\, m^}}$ (Taylor et al. 1993).
