Table 2

Variability statistics based on the Swift continua (XRT, W2, M2, W1, U, B, V) and on the combined B and V light curves (Swift, SALT, MONET, Cerro Armazones) in units of 10−15 erg s−1 cm−2 Å−1 and 10−11 ergs s−1 cm−2 for the 0.3–10 keV X-ray data.

Notes. In addition, we give the statistics solely for the dedicated campaign in 2015. Finally, we present the variability statistics based solely on the SALT spectra with their small aperture. In the second column the variability statistics is given after subtraction of the host galaxy flux.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
