Seeing statistics for the entire Orion A survey. The bottom row shows the normalized histogram for all three bands in bin widths of 0.05 arcsec whereas the top graph displays the cumulative histograms with a refined resolution. Most data have been taken during very good seeing conditions resulting in FWHMs measured on point-sources in the range between 0.7 and 0.85 arcsec for J and H; only K_S features a significant amount of data with point-source FWHM values ≳0.85 arcsec.
