(a) Profiles of the outbursts in the dwarf nova DX And (observations from the AFOEV database). One-day means were connected by a line in densely covered parts for convenience. The individual outbursts were shifted along the time axis to match the decaying branch of the template—the time of crossing 12.8  and the shifts with respect to the template are listed. (b) The relation between the peak magnitude of the outburst and the slope of its rising branch in DX And. The slope (rate of rise ) is expressed in days . Adapted from [4].
