A Circular Statistical Method for Extracting Rotation Measures
We propose a new method for the extraction of Rotation Measure from spectral
polarization data. The method is based on maximum likelihood analysis and takes
into account the circular nature of the polarization data. The method is
unbiased and statistically more efficient than the standard procedure.
We also find that the method is computationally much faster than the standard
procedure if the number of data points are very large.Comment: 17 pages, 5 figure
