Left: comparison of the relation between the integrated Hα flux, F_broad, and velocity separation between the blue and red peaks, ΔV = V_B − V_R, for three different monitoring campaigns. The data from the present work are shown as blue circles; the data from Storchi-Bergmann et al. (2003) are shown as red triangles, and the data from Schimoia et al. (2012) are shown as green squares. The comparison shows that during this campaign F_broad remained at the lowest fluxes ever seen while V_B − V_R was at a very large separation. This trend is in agreement with that of the previous observations. The blue dotted line represents the linear regression for the data from Schimoia et al. (2012) + that of this work (r ~ −0.343); while the dot–dashed line is the linear regression for the data from Storchi-Bergmann et al. (2003) alone (r ~ −0.823). The black dashed line is the linear regression for all the data together (r ~ −0.354). Right: three representative profiles of each of the three time periods covered by our previous and present work.
