Notes. The table lists (for the observing epochs of Table A.1) the brightness of the comet in SDSS r, SDSS i, SDSS g filters, measured in circular apertures of 1000, 5000, 10 000 km diameter (at the distance of the comet) centered on the central brightness peak in the cometary coma. The typical maximum uncertainty is ±0.03 mag for brightness of up to 16 mag, and ±0.04 mag for fainter magnitudes.
