The plotted Corrected Flux vs. Time data (converted from NASA's K2 raw data by A. Vanderburg) were accessed by starting with his website https://www.cfa.harvard.edu/~avanderb/k2.html.  RED points are the major eclipses; YELLOW points are the minor eclipses.

10 MAJOR Eclipses (E_5 missing due to a large data gap):
Period: 7.0776 ± 0.0006 days.
T_0: 1980.4791 ± 0.0040 [BJD-2454833]
Depth: 114031 ± 5723 ppm.


11 MINOR Eclipses:
Period: 7.0775 ± 0.0004 days.
T_0: 1983.6649 ± 0.0021
Depth: 34960 ± 5048 ppm.


PHASE: 0.4502 ± 0.0005 (an indication of elliptical orbits).

Stellar Rotation Rate: 5.47 ± 0.12 days.

                          Kepler K2-C1 EPIC-201158453: Eclipsing Binary

Discussion:
One or both of the stars in this eclipsing binary system show considerable surface activity; one of the rotation rates (or, more precisely, the frequency patterns of probable-repeating star-spots) is listed below with the other data.  It appears that the eclipse times are unrelated to stellar variability suggesting that the EB is a "detached" type.
