Notes. The table lists (left to right columns): the date of observations in UT, the filters combination, the amount of field rotation in degrees, the individual exposure time (DIT) in seconds, the total number of exposures, the total exposure time in seconds, the DIMM seeing measured in arcseconds, the correlation time τ0 in milliseconds, the variation of the flux during the sequence in %, and the true north (TN) offset in degrees.
