Comparison between radio light curves of Ross 867 as measured with the GMRT at 610 MHz during observations in 2007 (lower six curves and axis) and 2011 (upper two curves and axis). All neighboring points are connected with lines to help guide the eye. The vertical error bars represent the flux density measurement uncertainties. The time ranges of the snapshot image in which the flux measurement was made were ∼0.40 and ∼0.15 h for the 2007 and 2011 observations, respectively, and are shown as horizontal error bars in the legend. The dashed horizontal lines indicate the average continuum flux density of Ross 867 as measured in the image from the full time range.
