Figure 5: The light curve of GRB080319B acquired by TORTORA wide-field camera. The gamma-emission started at  s and faded at  s. Full resolution (0.13 s exposure, gray lines) data are available for all duration of gamma-emission except for interval of REM telescope repointing , while low-resolution ones (summation of 10 consecutive frames, 1.3 s effective exposure)—for the whole time. The light curve is approximated by a four nearly equidistant flares; lower panel shows the residuals of such approximation.
