Hi I am new to the list - and to using Astrometrica. I downloaded a new copy of the installation file and installed the software - having removed the old copy...
Donna, please give me a few hours time. I am currently at work in the office. I will send you the solution in a private Message when I return home later today....
Hello, this is my first post on this group, so I send a virtual strong handshake to all. When I blink images not perfectly centered on the same field of view ...
Dear Emiliano, you do nothing wrong, it is a wanted feature. Just imagine you blink three images, which partially overlap. Now there is a new minor planet in a...
Hi Emiliano, try to increase the Alignment area and/or n° of stars in the Program Menu of the Settings of Astrometrica. Regards, Luca Buzzi # 204 ... Da:...
Hi Gert, to know your real focal lenght, if you have'nt just done, let a try to this: get one image of a known angular separation (e.g. the angular separation...
Hi Luca, I think that the problem that was talking Emiliano it is not about a wrong alignement during blinking. He was just talking about the black stripes...
I would like to suggest that if the black areas are causing problems with the blinking, shrink the window and use the slider bars so that only the common area...
Dear Herbert, my opinion is that when you get the fields with single exposures (not a set of images to stack) three images are the minimum you must have to...
Hi Fabrizio, yes, I've better understood Emiliano's answer only when Herbert replied... ... Strange that I've not understood a question from an Italian guy...
Dear all - I have successfully completed the astrometry on a bunch of images using the USNO B1.0 catalogue. However, I am now trying to do the same thing on...
... You can't do that, but you can download a portion from a USNO server (http://www.nofs.navy.mil/data/FchPix/), store it in a file, and use this. Or you can...
Dear Herbert - ... Yep - this is exactly what I was trying to do. Could you please send me more information on how to achieve this, including which checkboxes...
Lisa, If you would be interested in obtaining the B1.0 catalogue on hard disk drive, drop me a mail to adsl7117 at tsn.cc Vincent ... From: lmgermany To:...
Before getting USNO-B1 on a hard drive, be aware of the USNO NOMAD catalogue. Hopefully Herbert will enable NOMAD access in Astrometrica in the near future....
Regarding USNO-B 1.0 and NOMAD, there was an interesting discussion at the German meeting of asteroid observers some weeks ago in Berlin. L. D. Schmadel from...
Hi Herbert, Just the curiosity. Considering that Nomad is a hierarchical merging of catalogs and that those catalogs seems to have systematic errors... Why...
I have certainly noticed relatively fixed offsets at times between B1 and UCAC2. But it is not a trivial exercise to compute that offset on a routine basis....
On the issue of dealing with systematic errors. The NOMAD catalogue is a mere compilation of catalogues. Any and all 'errors' in the individual catalogues are...
Herald, Who was it that asked for your opinion? Vincent ... From: Dave Herald To: Astrometrica@yahoogroups.com Sent: Monday, August 20, 2007 11:57 AM Subject:...
... Lutz Schmadel said that the systematic errors probably are due to the proper motion data. The proper motions are not in a fixed reference frame, but are...
Vincent, even if no one has specifically asked Dave for his opinion on USNO-B, I think that is comments are still interesting for a number of users in this...
Herbert, Sorry, I don't agree, so goodbye. Vincent ... From: Herbert Raab To: Astrometrica@yahoogroups.com Sent: Tuesday, August 21, 2007 9:03 AM Subject:...
I myself have nothing to add to this discussion. I concur with Herbert that Dave's comments are always knowledgeable and of general interest to many of us. The...
Just for the record, I thought I should note the following: I first learnt about the NOMAD catalogue at a EuroPlanet Workshop held at Paris Observatory in...
Nobody asked for yours, either. -John ... ____________________________________________________________________________________ Shape Yahoo! in your own image....

Dave, ... each time somebody asks or recommends to use the B1 locally you come with your "Nomad is better" argument (this thread is not the first on this...
NOMAD is available in exactly the same way as USNO-B1. Either over the internet from Vizier etc [The Vizier catalogue number is I/297] - which is the ideal way...
