sorry, it should've been "a dozen years ago"!!!!

yup, Chris Lloyd used to do some stuff on this, and indeed I still couldn't
calculate Sterne's chi squared statistic for O-C data without a little DOS
executable he let me have ages ago.   He's also responsible for the best
constructive refereeing I've ever had!

I did mention Foster!

I've read most of Percy's work, and not mentioning it was not an oversight.
 I'm interested more in the visual stuff than the PEP stuff.  Also, on the
visual stuff  I personally don't like this lumping of Galactic Miras
together for statistical assessment.  We don't live in the LMC, where such
approaches seem to work, and stellar populations here are more complex and
frequently ignored as part of the equation.  And all this despite work by
Kerschbaum and/or Hron, and, Jura and/or Kleinmann. No, Percy's LPV
analysis work wasn't mentioned cos it wasn't mentioned.  His current spate
of suggested period evolution in RV Tau stars due to a miniscule dogleg in
their O-C plots should worry you as much as it worries me!

Hopefully I'm no longer "dotty" in this mail [don't all go taking a vote on
it!]. I'm fathing about with new/different mailing software at the mo'. I
want _completely_ html free, _text_only_ emails arriving at this end, no
matter how it's sent and from whatever platform [and despite what the
megalomaniac from Seattle thinks I should want (allegedly)]

>Best wishes -- The original John. 

hmmmm, as I'm named after my paternal grandfather, who was born at the turn
of the century, I'm not sure about that, unless you are very old after all?
;^)

PS

John, I believe you are somewhat connected with AAVSO nowadays.

Could you think about encouraging them to have the technical papers that
make up part of each JAAVSO proffered for archiving at the NASA ADS?

For example, someone who is currently seriously improving on some GCVS
based LPV periods recently noted to me that they'd go for a JAAVSO
publication when the task was completed, because the dreaded LaTeX made
IBVS publication problematic.

One of the reasons given was that SIMBAD [and indeed the ADS] included
JAAVSO publications in the bibliographic servers, so it should be
accessible to the wider community that way.

Now, that is true, but usually there isn't even a copy of the abstract for
JAAVSO stuff in this bibliography, and JAAVSO isn't on every library's
shelves by a long chalk.

So, if anybody comes across a (say) twenty year old reference to an article
on a variable in JAAVSO, unless they've been a subscriber since that time,
they are very unlikely to get to see that article [few of us can afford to
order back issues of every reference we come across].

Some good stuff has been published in JAAVSO over the years, and I think
the archiving of past technical papers from JAAVSO at the NASA ADS would be
a serious contribution to the variable star community.

Anyway, just a thunk.

Cheers

John
