  Yup, this is already in queue for the output from ARNE.
In fact, I am supposed to be taking a disk of data to
the chart meeting in Hawaii in two weeks; we'll see how
far I get.
  Note that the current photometric accuracy of CD23
is still suspect at the 0.05mag absolute level, so while
it would be an improvement over most of the older AAVSO
chart sequences, they are waiting for better photometry
before going through the effort of revising things.
Also, many of their charts are for variables in relatively
crowded fields, so the TASS photometry has to be checked
pretty carefully for blends.
