Table 2.

Details of the Swift UVOT observations made in 2006 Jan 5 and 6 where we indicate: the filter and its central wavelength; the mean count rate and flux; the rms derived from the given number of points. We also indicate the expected rms_exp which is determined from the mean count rate and sfrac = rms/Rate. We also determine sfrac for two different bin sizes and were derived from the event data.
