Two EAs, unsure if caught secondary minima or not

I have attached phase plots for two EAs. In both cases, the SuperWASP amplitude differs significantly from the ASAS-SN and ROTSE3 amplitude. Based on the plots, does it appear that the ASAS-SN and ROTSE3 data have captured the primary and the SuperWASP data only caught the secondary? If only the primary was recorded by all the data sets, why does the amiplitude of SuperWASP differ by so much?

Hi Nicole,

Hi Nicole,

Did you deblend your SuperWASP data? It has much larger aperture. A contamination might have caused SWASP eclipses look more shallow.
