    thank you in advance.

    Let's see, a glitch could be thought of as a small problem either starting at the spacecraft or from one of the data compilations back here on Earth (usually the former so as not to blame anybody). Noise I would say is thought of as more stellar in nature, either from the star the spacecraft is looking at or caused by one of its brighter neighbors. But occasionally light curves are just all glitch type noise too. And the other problem with glitches are they sometimes look like transits and so individual dips should be looked at with a little extra bit of caution because of this. I hope this helps.

    thank you very much.
    i am having another question.
    often i see the hashtag simulated. does that mean the data is not from a real star?

    I believe so, that simulated data are not real but computer generated transits.
