    Hi David,
   
    I'm not sure what to make of the difference of the wiggle between
    the two methods, but it seems that "coordinate option" with
    "centroid" enabled is the easiest way to go if your images have WCS
    headers (i.e. have been plate solved). That saves having to merge
    the two measurements tables.
   
    Yes, when a meridian flip physically occurred during observations,
    the meridian flip detrend parameter should be enabled when fitting a
    light curve model, especially if there is an offset in the relative
    flux at the flip time in observations. It doesn't matter when the
    flip occurs, but you must place the meridian flip marker at a time
    between the last exposure in the east and the first exposure in the
    west.
