V1184 Tau optical and near-infrared light curves vs. Modified Julian Date (MJD). Red points are new infrared observations, while black points are literature data. Vertical black lines indicate the periods when mid-infrared data have been recorded. The corresponding telescope is also labeled. In the second panel we show, as an example, the fit through the V light curve. The maximum and minimum values of the fit are assumed to be V magnitude of the low- and high-state of the source, and used to construct the corresponding SED (see Sect. 3.2).
