  I am sorry, but I never understood those graphs. What are they telling us?

  1: The first image LC(SAP_FLUX) is at presentation of the raw data instead of PDCSAP_FLUX which is processed data as here on PH. A good planet candidates should show transits in both SAP_FLUX and PDCSAP_FLUX.
  2: The second image SAP_QUALITY tells us something about the quality of the data. For example, '8192' & '128' at the following link shows us that two dips within the transit event are caused by hits of cosmic rays. If we had seen '36' it would be a data break, and so there are different numbers for different problems: http://talk.planethunters.org/#/boards/BPH0000005/discussions/DPH00001qk?page=1&comment_id=541e78177a56b631df002a56.
  3: APO means 'active pixel offset' and has something to do with contamination. Dips could possibly be caused by blended light and the real dip could actually come from a nearby star.
