Default pre 2006 catalogued FASTT candidate variables in Nicholson's"uncatalogued" red variables' paper



the following facts about Nicholson's "new" objects in
http://www.aavso.org/publications/ejaavso/ej96.shtml are archived here

http://ooruri.kusastro.kyoto-u.ac.jp...ly/000395.html

quote :-

"And of course, when we use VizieR in general and/or B/VSX at VizieR
specifically we find Henden and Stone candidate variables matching
some
of his "uncatalogued" objects, ones that not only long pre-date 2006
as
publications but also have been in VizieR for way longer than that.

No real surprise, same old story.

Checking around Nicholson's 2MASS positions using a 30 arcsec radius
we
find some of them are actually still in AAVSO VSX as FASTT objects
only,
and not listed as VSX_Jetc (which is how new objects entered into
AAVSO
VSX are monikored, ie the identifiers for new entries not in other
catalogues are denoted with), thus the claim in his paper that the
mentioned stars therein are in AAVSO VSX as his doesn't always hold up
particularly either.

There are other catalogue variables too in the uncatalogued list, more
than for FASTT ones (some are actually catalogued both in FASTT and in
other variable star catalogues), although they apparently got into
print
after 2007 January 1st, and even later into VSX, but apparently he was
able to get spectral types from a Skiff 2008 VizieR holding, but not
able to look up for already published objects?

Sounds standard so far.

So, he missed Uncle Arne's long catalogued MISC and LPV and made them
his own L, which is GCVS speak for MISC, and published 'em in an
ejaavso. Nice touch of the old irony there. Well, it's only around a
dozen, so I suppose that's only ~ 1%.

Simply based on sticking Nicholson's spreadsheet list's 2MASS
positions
into VizieR and using B/VSX and checking the decimal RA and Dec for
multiple hits to ensure they're the same object.

Oh, and just so he knows, some random checks show fastt candidate
variables look to be pretty much fully included in SIMBAD, which he
also
tested, if not under their own name you have to check the bibliography
for each one, it's called doing the literature work and not just
automating the crap out of everything and simply jiggly spreadsheet
columns around. In depth literature and follow up work, not just
using
simple listings checks, are often essential. Although I found this
out
simply by using simple listing checks on AAVSO VSX.

Top quality stuff that paper, needs pride of place on the aavso data
section methinks, alongside the Utasov list of NSVS red variables,
with
which it might share one or two too.

Same old same old, same old uncatalogued and new but his usual lack of
effort to ensure it is such, same with variables, same with common
proper motion pairs in the past usually quoted as being not in WDS but
being something like evident LDS and Giclas cpm pairs, because, ya
know,
high proper motion means they've moved a bit since the epoch of the
first measured positions, if only by definition. You only ever have
to
do a quick skim of his stuff to find misses and contradiction to the
papers' assertions all over the place.

SUMMARY : ejaavso 96 claims to have done decent literature checks for
objects catalogued prior to 2006 yet somehow missed the current aavso
director's objects that were so catalogued, and in vizier, way before
this, in both catalogues the objects are flagged as miscellaneous
variability, mostly, in fact Henden and Stone's list actually classes
some of the common objects as likely LPV (P for periodic), which sure
as
hell ain't L.

John Greaves

I dunno, variable star stuff in general, fudge, twist or fib or claim
half a ton of unfounded whatever and it's fine, or give "jam tomorrow"
promises or unsupported reassurances, but spout half an ounce of truth
and yer evil. Feh, I'll see some on topic posts one day maybes, that
is
ever I ever bothered to look.

Really ain't gonna miss variable star stuff coz there ain't much
really
worth being missed.

I shall not bother finding the constant stars in it then, coz y'all
ain't interested. Let some bugger else do it.

And as for Nicholson whining about topic, Mr invent a new blog and
selective edit and quote out of context, well, he's never realised
some
folk say nastier stuff about him behind his back than he does about
other people behind their backs, and far nastier than I've ever said
about him in public."

Of course because his catalogue is stored on his own web site he can
find those FASTT variables of Henden's that predate his 2007 check of
the databases and remove them from his list but as he has quoted a
total figure of new variables in his paper he will have to find
something to replace them with.

Marvellous accomplishment though, publishing as new in an AAVSO
journal objects discovered and published over ten years earlier by the
current AAVSO director. An impressive achievement.

Default Greaves moderated into silence by yet another group

Dear colleagues,

Quite unfortunately, John Greaves does not seem to stop posting
articles meaningless, or even unpleasant to most of the VSNET
subscribers, in spite of repetitive kind advices. We then
decided to set a mail filter for John's posts. We are very sorry
for our late decision.


Running out of places to post are we John?
