1 Otero, Sebastian Alberto Min II= 12.51 V. The largest period change (increasing period) in the sample of 41 triple system candidates in 2012AJ....143..137G. The period in the table was derived from all Kepler data, that were not yet available at the time of the paper publication (the period in the paper is 3.00352 d.). The period combining ASAS (2006-2008), NSVS (1999) and Kepler data (2010-2013) is 3.00360 d.
