Downtime expected shortly as all LEDAS services are moved to a new server.
AR Lac deconvolution
These images show the results of a deconvolution of the ASCA lightcurve
taken of the 2 day RS CVn binary AR Lac and compared with a similar
deconvolution of an EXOSAT lightcurve taken 9 yr earlier. The distribution of
coronal material in the system can be seen. A large structure seems to join the
two stars in the ASCA observation, which was less obvious 9 yr earlier.
