Toward selection of intermediate-magnitude polarization standards
The Minipol optical polarimeter with a V-band filter was used to observe16 summer intermediate-magnitude (mB = about 9) stars from the survey ofMathewson and Ford (1970). These stars were chosen to span polarizationpercentages from zero to almost 6 percent and to cover a large range ofpolarization position angles. The primary reason for reobserving thesestars was to determine their V-band polarization properties and toidentify polarization variables, which are unsuitable standards. TheMinipol observations showed that 12 of the stars had V-bandpolarizations that were very similar to the Mathewson and Ford B-bandvalues. One star had a significantly different polarization positionangle and two had significantly different percentage polarizations. Onestar, HD 161306, was wildly different in both percentage polarizationand position angle.
