This K2 star

  • PJYoung by PJYoung

    I realise this is probably ignorance on my part, but I am a bit surprised by this chart. The Y axis covers a long scale and shows what to my untutored eyes appear to be massive drops in brightness around day 1 and 2? Is this normal for this kind of star? Practically all of the other light curves I've looked at only fluctuate across a much smaller scale.

    You are right, the Y axis is completely implausible. The curve below for this star shows lots of spikes and dips, which are surely glitches or contamination.
