![]() Leading expert amateurs in the field of variable star astronomy from Britain, the rest of Europe, America, Australia and New Zealand agree that the papers Eclipses of OY Carinae in Outburst http://www.aavso.org/publications/ej...v37n1/40.shtml Consecutive Eclipses of Z Chamaeleontis in Outburst http://www.aavso.org/publications/ej...v37n1/36.shtml have little or no meaning, being at best the reporting of a couple of ToM (Times of Minima) each. This was the honest and considered opinion of eight people, three quarters of whom are AAVSO members, and three quarters (with some large overlap between the two sets) of whom have published papers based on variable star period analysis to their names, and over half of them having in the literature papers based on O-C work and heavily involved in the archiving and recording of ToM work for national and larger regional groups, and nearly all of them hold positions and/or maintain active roles within four or more regional groups. One of the European experts even asked the AAVSO Director if this precedent meant that the eJAAVSO would now be regularly publishing papers based on what amounted to little more than a couple of ToM. For those unfamiliar with variable stars, publications of ToM work usually include many ToM, as for example in this eJAAVSO Recent Minima of 154 Eclipsing Binary Stars http://www.aavso.org/publications/ej...v37n1/44.shtml All the experts agreed, indeed several stated without prompting, and actually brought the point up themselves bringing it to attention, that the OY Car and Z Cha papers had no meaning other than the stating of the times. The other points made in the paper had no meaning within either the scientific context or the specific observed minus calculated procedure. Yet it seems to highlight this point is to have people sympathise with Martin Nicholson and suggest to him that as an AAVSO member and publisher of the papers he should report this matter to AAVSO. The AAVSO Director was already well aware of the issue, as already stated an experienced and well known European AAVSO member, involved in both the archiving and processing and analytical use of much ToM work for more than one major European group, had already expressed their strong concern to the AAVSO Director in an email with respect to the dedication of entire articles to the publication of papers that had little content other than the two ToM measures involved in each. Some quarters are not entirely happy that JAAVSO has gone electronic only. Yet there is no problem there, printed copies can still be ordered via print on demand, and fully formatted PDF articles can be freely downloaded for use. The bigger concern is whether JAAVSO will maintain a reputation for scientific work. As stated eight experts in the field could not see why these papers were published, and were not impressed with them. Nearly all were AAVSO members and at least one of these members expressed their concern on the matter to the AAVSO. If an amateur astronomer or an amateur astronomy group wishes to claim scientific credentials and a reputation for scientific work it is not a simple matter of running crying to teacher telling tales if someone advises on an open list that this publicly available material is not scientific. The papers cannot even be refuted via publication as they are not even wrong. O-C cannot be used to confirm or refute elements in the way stated. Anyone knowing or having done any O-C work will be well aware of this. Isolated lone points in O-C are not really even O- C, the sum of all known O-C points have to be investigated. The sad history of IYA2009 in the English speaking variable star field may well consist of a large number of claims of extra science being done this year with very little evidence to support it. Hopefully the wider aspect of IYA2009, introducing many people to their first sights through a telescope, will have more than made up for this. However, if the veteran and experienced community wishes to make claims about being grown up and scientific it has to do a proper job of it. For the professional community will soon notice slapdash work. The professional community don't even acknowledge amateur scientists properly a lot of the time when the amateur astronomer has done good. Take the recent impact scar on Jupiter. Anthony Wesley discovered and noted the similarities of this scar to SL9 impact scars from fifteen years ago. Press releases from big observatories using sophisticated equipment also say it is an impact scar, but still only by comparing their data to their experiences with the SL9 event. Anthony Wesley needs to be strongly congratulated for not only noticing the scar, having the experience and knowledge to differentiate it from the many transient spots and blemishes Jupiter's atmosphere exhibits, but also for noting the similiarity to impact events. http://jupiter.samba.org/jupiter-impact.html (scroll down and read the observation report) Yet several press releases from the big professional organisations only credited an unnamed "amateur astronomer" for discovering the scar, and as of yesterday few if any repeated the point that Mr Wesley himself felt, after a process of elimination, that it was likely an impact scar, and informed people of the discovery because of this possibility, reaslising that if correct it would be a significant and important find and need monitoring as soon as possible (for impact scars change over time), else the big observatories would not have known so promptly. That is, as of yesterday he was not always credited for discovering the scar and announcing it, and was as far as can be seen not credited at all as having made decisions himself with respect to this likely being an impact scar within most of the press releases. If amateur work is not properly acknowledged fully even when it deserves to be, due to the occasional attitude of the professionals (all the press releases were very careful to mention the names and details of professional observatory staff and research group principle investigators when they released their images, for instance), then it is likely to get even worse if utter bunkum is presented and published in venues such that people can claim it to be scientific work, but professional will likely view it more as evidence of amateurs being, well, amateur. Alas poor JAAVSO? Hopefully not. It is needed by amateur variable star scientists to show their worth, so likely has a somewhat larger and possibly unfair onus upon it that most to be careful of such problems as unscientific work. And before the bleeding hearts start, it is leading AAVSO members and variable star period analysis experts from around the World who see no merit in this paper, and in some cases they have commented upon this to AAVSO. So AAVSO knows, it doesn't have to be told, but you can complain to AAVSO if you wish. The bleeding hearts have got to remember that this person posts links bragging about his scientific work everywhere. He mentioned one of these papers on the GRAS forum to make a point that he was doing meaningful work whilst other GRAS, which he seems to have fallen out with recently and made sideswipes about on various blogs and websites, users weren't. http://forums.global-rent-a-scope.co...861&#entry1861 Yet despite his subtle sideswipe about "Varaible Stars - What Is Going On?" as a sneaky attempt to show off his paper, his paper is dismissed by AAVSO members who are experts with true publishing track records, and they are still actively in involved in many projects today, they just don't brag about every little thing. In the end it is not about the personalities it is about the science. If there is no science and amateurs are even dismayed or at least unimpressed that JAAVSO should publish such things, how are professionals expected to be any different? |

Greaves has campaigned against the American Association of Variable Star Observers (AAVSO) for some years now. Curiously, as far as I can tell, he has never been a member of the AAVSO so exactly why he should feel so strongly about the activities of the Association is a total mystery. A manifestation of his life on State benefits perhaps? Two recent examples of a typical anti-AAVSO Greaves diatribe can be found here http://tech.groups.yahoo.com/group/AVSON/message/1765 and at http://tech.groups.yahoo.com/group/AVSON/message/1760 How curious that none of the people Greaves has claimed as supporters of his many and varied anti-everything views has ever had a name - this going back as long as folk can remember. |

The biggest mistake you folks keep making is dragging out your frustrations
in a public forum. You not only help to incriminate yourselves, but lose respect for both you and your arguments. This debate should have been carried out either in private emails, the telephone or even in person and not here. "astropapers" wrote in message ...
