MAST Archive

The link below is the MAST archive for KIC 8462852.

The Mikulski Archive for Space Telescopes (MAST) is a NASA funded project to support and provide to the astronomical community a variety of astronomical data archives, with the primary focus on scientifically related data sets in the optical, ultraviolet, and near-infrared parts of the spectrum. MAST is located at the Space Telescope Science Institute (STScI).

When you see the main page for KIC 8462 you will see the tab for the Home Page and the MAST:KIC462852 Observations.

In the Filters Column you have numerous selections to choose from

1. In the Mission Filter select Kepler.
2. In the list view you will see results for the stars that have been studied in this region of space that shown on the AstroView to the right hand side.
3.Click in the box for the first result and the box around KIC 8462852 is highlighted in the AstroViewer.
4.Click the the icon next to the save disk icon in under the Actions column. This will open up a Timeseries Viewer that will allow you to look at the time line series for the dip that you have selected from the Legend on the right hand side of the viewer.
5.Under Options select a Smooth Factor of 14 and Lines and Points from Style to generate the series. Select the KPLR_008462852 LC Q00 SAP box in the Legend.
6.The left side of the graph is the amount that the stars light has dipped or increased over a certain time below which is at the bottom of the graph. In this case the first dip that you see was a decrease in the light curve of KIC 8462852 was 0.00031 or 2.30993 - 2.30962. The dip lasted ~ 12 hours and then spiked again a few days later by ~0.00062%
7. Going back to the List View. You can see that a lot of the stars have not been identified yet but some like the three Red Giants have been.
8. You can selected multiple targets of interest in the Edit Columns. You can also select a target of interest by clicking in the square where a pointer will appear relative to KIC 846285.
9.Un select all of the boxes except for number one

Planetary Candidate
1.Scroll down until you find target 73 which is KIC 8397947.
2. Click the Timeseries Icon.
3. Adjust the Smooth Factor to 14 and the Style to Lines and Points.
4.Notice the dips in the light curve at days 7.438 and 22.315?
5. To very this is a planetary transit multiply the lowest dip of the first light curve by 2. Why by 2? Because the distance from the first dip to the second dip is ~ 14 days, so that would be 7.438 x 2 = 14.876. Next add 14.876 with 7.438 = 22.315 which puts the second transit within the range of day 22.315.

Thing is, its not really worth the effort to bother doing anything but the easiest ones, most of the time i just sit there spamming "no transit" while looking for the obvious test data, you don't actually get anything for agreeing with the consensus and they aware the same payout
