Tales of Cataloguing -- epilogue
In the end, I did make those "Tales of Cataloguing" (quasar positional
fixes posted here in October 2011) into a paper, now accepted by PASA. It can be seen at http://arxiv.org/abs/1206.1144 . cheers, Eric Flesch Wellington, New Zealand |

It can be seen at http://arxiv.org/abs/1206.1144 . cheers, Eric Flesch Wellington, New Zealand quote 380 objects for which I find that the VCV position is offset at least 8 arcsec from the true optical position which I present. 31 of these quasars require a move of at least 10 arcminutes. end quote Are you sure that NONE of those object *moved* ??? "Expect the unexpected"... Try again in a few years some of those 380 objects. P.S. I know I know, "Impossible", quasars are too far away, whatever. But... observations have the last word! :-) |

Ha ha, you can check that for yourself, Jacob, by looking up any quasar on the Digitized Sky Survey at http://archive.stsci.edu/cgi-bin/dss_form Check the object in turn on a POSS1 plate (1950s-60s epoch) and also on a POSS2 plate (1980s epoch) and report back here if you see any moving quasars. :-) Eric |

..... to which I would like to add that, had I ever seen a moving
quasar, believe me, I'd be jumping up & down and pushing it in the faces of absolutely everyone. Martin knows I would. But never a moving quasar have I ever seen. cheers, Eric [Mod. note: Completely agree! -- mjh] |
