We have placed online updated f-scale charts for SN2002ap using the
latest Henden data:
http://vsnet.aavso.org/charts/PSC/SN2002AP/
When sending observations of this object it is vital that one include
chart or comparison star data. The values given in the new sequence are
generally brighter than before so mixing observations made by one chart
with one made with another chart will resort in an artifical brightness
increase in the lightcurve. Any major shift in the decay/brightening rates
can make a significant impact on the astrophysical modeling of the system.
Please be careful to describe which chart or comparison stars you are
using.
