Pathfinder exploration 2: Can we see hints of starspot contrast "Locus" in the pathfinder sample?

Recreate the plot from the proposal:
fig2.pdf

The black points should be the K2 "EVEREST" points, with plot coordinates $(x,y)$ representing (Period EVEREST, Amplitude EVEREST).

Then, plot the TESS points as different color dots, with plot coordinates $(x,y)$ representing (Period TESS, Amplitude TESS). Our prediction is that those TESS points should fall in the orange region.

Was our prediction correct?? Why or why not? Do we need more data to answer?

Hooray! @RyanHartung just made a discovery!!

Comparing to the theoretical prediction:

Changes:

• Add legend for black and red points for graph above
• Only show points for Kepler that have corresponding TESS data
• Create mask that only includes data relatively close together on the comparison between amplitudes (bad_mask1=df.tess_period < df.kepler_period*0.8 AND bad_mask2=df.kepler_period< df.tess_period * 0.8 AND remove all data above period 7 AND df.tess_data.is_finite)
• Regenerate the fig2 plot with new mask added
• Find mean amplitude of Kepler and TESS and find the ratio between them for fig2 plot

Science Takeaways:

• Yes! Our prediction was correct
• It was correct since all the stars fell below the Kepler data
• Predicted to show a decrease by about 3, we found a decrease of about a factor of
• We need to clean the data, which we will get once we have access to Eleanor-lite

Here is the new plot with updated graphics and masks:
