No evidence for [O III] variability in Mrk 142.

BARTH A.J. and BENTZ M.C.

Abstract (from CDS):

Using archival data from the 2008 Lick AGN Monitoring Project, Zhang & Feng claimed to find evidence for flux variations in the narrow [O iii] emission of the Seyfert 1 galaxy Mrk 142 over a two-month time span. If correct, this would imply a surprisingly compact size for the narrow-line region. We show that the claimed [O iii] variations are merely the result of random errors in the overall flux calibration of the spectra. The data do not provide any support for the hypothesis that the [O iii] flux was variable during the 2008 monitoring period.
