The listing gives the UT time and date, the name of the star being observed, the and the secant of the zenith distance. It then lists the number of measurements ('n') done in a one minute interval, the FWHM seeing measured longitudinally in the subapertures (l), the average of long. and trans. measurements in arcsec ('Seeing': this is the one you care about), the FWHM seeing measured transversally in the subapertures ('t'), the flux, the equivalent r0 (in cm), and the differences in columns ('dX':should be near 85) and lines ('dY': should be near 0) between the 2 images.
