Abstract
Light sterile neutrinos, first proposed after the results of the LSND experiment, have been a polemical topic for the last decades after seemingly contradictory data appeared from different experiments. In this overview, I review the experimental hints that point towards sterile neutrinos as well as their statistical compatibility. Even though the muon neutrino disappearance experiments strongly rule out vanilla sterile neutrinos, each oscillation channel remains internally mostly consistent. In any case, in the near future a series of independent and precise experiments should finally settle down this issue.

None.
Report
This paper gives a superb overview over the hotly debated issue of sterile neutrinos. The author very nicely weights all evidence pro and contra. It is well written and clear. I have one question to figure 7: the first two data points are both labelled GALLEX (51CR L = 1.9m), so what is different between these two points?

(in reply to Report 1 on 2018-11-27)I gratefully thank the referee for his/her careful reading and comments. Answering the question, in Figure 7 the two GALLEX data points refer to measurements with two different 51Cr sources. The particular references for each measurement are
