Comparing 3 smaller subsets of M82 data

• I have broken the 57 pointed corrected M82 polarization cycles into 3 equal subsets of 19 files. These are simply grouped in chronological order, no attmept has been made to order them in any other manner.
• All vectors have ΔP<2%; Red vectors are between 2-3σ, green vectors are 0-2σ. Vectors are plotted every 4 pixels (~10 arcsec).
• The three individual subsets are labeled "set1.fits" - "set3.fits." The image with all 57 files is labeled "all.fits".
• Note that the two peaks are best separated in set3, likely indicating that there are still some pointing offsets embedded in the data.
