Query: The DRAO 26-m Large Scale Polarization Survey at 1.41 GHz   The Effelsberg telescope as well as the DRAO synthesis telescope are
currently surveying the Galactic polarized emission at 21 cm in detail. These
new surveys reveal an unexpected richness of small-scale structures in the
polarized sky. However, observations made with synthesis or single-dish
telescopes are not on absolute intensity scales and therefore lack information
about the large-scale distribution of polarized emission to a different degree.
Until now, absolutely calibrated polarization data from the Leiden/Dwingeloo
polarization surveys are used to recover the missing spatial information.
However, these surveys cannot meet the requirements of the recent survey
projects regarding sampling and noise and new polarization observation were
initiated to complement the Leiden/Dwingeloo Survey. In this paper we will
outline the observation and report on the progress for a new polarization
survey of the northern sky with the 26-m telescope of the DRAO.
