Notes. Date is a UT date for the beginning of observation; JD denotes the observational interval during current night; N – number of observations; φ_i, φ_f – orbital phases corresponding to the beginning and end of monitoring; m_min, m_max – minimal and maximal brightness during the observing period (the observed differential magnitude ΔC of A0620−00 with respect to its primary comparison star in white light filter, and J and K magnitudes in the near-IR). In the last column, we designate the data series as filter and monitoring night number (as JD−2457000) which is used to distinguish data in the light curves in Fig. 2. Photometric data will be published later and are available upon request.
