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 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." |

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

Greaves moderated into silence by yet another group
Read this
http://ooruri.kusastro.kyoto-u.ac.jp...ly/002921.html 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? |
