(1992 Nov. 24)
subject: X-ray nova
The data have been reanalyzed using nearby faint comparisons to
remove the effects of non-linearity of the detector and/or the photometry
algorithm. The result shows better consistency in terms of the period
during the run of two nights. The revised period is 0.2249 day (least-
squares) or 0.2217 day (Fourier), which express the four maxima observed
well. The period is again different from the published value. The
amplitude was 0.10 mag. Together with the run on Nov. 23 (and subsequent
observations) we will be able to confirm the period to at least 1%
accuracy.
