Abstract
Low error measurements at the Arecibo Observatory (at 318MHz) of
the weighted average interstellar magnetic field projected on the line
of sight ![[FORMULA]](img1.gif)
and of the Rotation Measure in the
direction of several pulsars were done using a new method. This method
is based on the measurement of the period of the temporal modulation
in the linearly polarized component of the pulsar pulse observed in a
wide receiver bandpass. The error in the measurement of
and RM is about one order of magnitude
smaller than previously published measurements. Because of its high
accuracy this method will continue to be used for the monitoring of
the interstellar magnetic field in the directions to pulsars.
