The paper An overview of the photometric events, trends and brightenings of eta Carinae was published in The Journal of Astronomical Data 12, 3 (2006). The conclusion "If this assumption is correct, it would mean that the mass of the stellar wind envelope is growing linearly, thus, the mass loss rate per orbital cycle was, on the average, constant over at least the last 35 yr" in Sect. 5.7.2 is incorrect and should be ignored.
