Phase-folded Light Curves for Date Groups  

Since our SNR isn't sufficient for ruling out the presence of dips (at the 1 % depth level, for example) the following phase-folded LCs for observing session groups (of only "a few" days) will be our best product for assessing the presence or absence of dip activity.

Mar 25 - 27




Mar 03






The 2nd dip is really not detected.

Mar 03






Group Feb 27,28






Group Jan 25-27 











Group Jan 20-22



Adopted dip model fit for a LC for 3-day observing interval showing candidate dips and their statistical significance (sigma) and contribution to dip activity (EW).



Phase-fold LC for a 3-day observing interval showing two possible dips .
   

Group Dec 20 - 31



Phase-fold LC after combining all data for 4 days (5 observing session data sets) of the current group of observing sessions (using the A-system ephemeris).



Phase-fold LC after combining all data for the first 10 days of the first group of observing sessions (using the A-system ephemeris).


This LC shows no dips (> 1 %) when data are combined on the assumption that any dips that are present belong to the A-system (4.49126 hrs) and that they persist for the duration of the 10-day observing interval.
