Dear friends:
I have redone the photometry of the sn1998es (same unfiltered CCD image of
981117.808) just following the suggestions from Brian (I have previously
used USNO SA1.0 reference stars and the Astrometrica program) and I have
got a more realistic value of 14.2 +/-0.1
Thanks for your very useful remarks, Brian.
/Giuseppe
