Noisy dips APH00019fe

    Immediately after the first glitch there is a general group dip on this noisy curve. Can that indicate a transit?

    Just an opinion, but I would say anything near a glitch or a gap are a bit more suspect as transits.

    Thanks ajamyajax, It looks to me like a transit, but it would be good to know what causes a gap and whether or not it affects adjacent readings as you say.

    Sure, Kepler light curves are stitched together and then flattened by corrective software which usually works very well. But at times, this process causes small rises and even small transit-like dips around gaps which I believe can be seen in quarter 7-3 here for example. And gaps are just periods of time with no observations.

    Got it. I had just ignored those quarter notations before - 3 x 30 days makes a quarter. And I see what you mean about the dip. Much appreciated.
