Hello, I'm trying to stack images of a comet that is displaying a large coma region. The stacking routine seems to be getting confused when aligning the images...
Do the images have a common centre, or has the field shifted between exposures? I suspect the stacking works best when the fields are the same. If your fields...
... It's neither weird, nor is it one too many. Astrometrica does a full fit on the first two plates, because a fit of a single plate is less stable (no...
... Has the program always done this..? Wow, I guess I've been away from using the software too long. I don't ever remember this happening.. Ok, glad that's...
Hallo all, just a question about the new MPC format of submitted observations http://cfa-www.harvard.edu/iau/info/Conversion.html Herbert are you planning an...
... Yes, of course. Most of the work is already done. If you (or some- one else on this list) want a pre-release copy to test the new format, please let me...
... Before you start distributing copies, you might want to send me some observations output by the new program, so that I can check that the format adheres...
Gareth, thank you for your offer , which I will gladly accept. I will compile a few observations over the weekend and send them to you. Thanks a lot, Herbert...
... What about an online "MPCObs verify" service? Like the online "FITS file verifier" here: http://fits.gsfc.nasa.gov/fits_verify.html Or maybe the full...
... Hmm. Might be able to do that. Not all the necessary code exists atm, but I might be able to get something up and working soon. I'd have to start with a...
Dear friends Herbert and "Astrometricaers", I would appreciate your cooperation on clarifying a little doubt I have. Herbert, you told me that it is possible...

Hello, Getting the latest asteroid positions using "Download MPCOrb" would require an enormous amount of time & bandwith (~ 20 MB) and someone who still...
I believe that Astrometrica does just updates to an existing MPCORB.DAT, it does not try to download the whole thing. I may be wrong, though. The zipped ...
... Astrometrica can access the original USNO-B, as distributed by the USNO on hard disk. I don't know if/how the above versions differ from the original...
... For that reason, Astrometrica does (unlike any other software I know of) offer to update the MPCOrb, without the need to down- load the complete database....
... A *temporary* designation. The *provisional* designation is still returned by the MPC, at least if the "designation emails" do arrive now and then ;-) R....
MCPORB is a file of elements in MPC 1-line format and you will need it for track and stack and the ID list and the known object overlay. For NEOs there is a...
... Me too! Don't know how many thousand times I have renamed MPCORB:DAT and my userelements file so far to switch between them:-( Astrometrica should accept...
... Herr Raab, Have you ever consider to distribute Astrometrica on a cdrom along with the USNO-B1 and/or the GSC catalog? A full ready-to-go pack (speaking ...
... Astrometrica does not work with any GSC version and the USNO-B1.0 is unfortunately pretty large, distributed on a 120GB (?) hard-drive or so ;-) Noroc, ...
The GAS catalog is not generally used now, the accuracy is not in the same class as the newer catalogs and the USNO-B1 is 82 GB in size which is over 100...
... GAS? ... http://ad.usno.navy.mil/ucac/ ... The final catalog is expected in 2006. ... I suspect this means at the GA in 2006, similar to the availability...
I've just checked the USNO web page. They state that the final catalogue should be ready some time in 2006. Given the delays that occurred with the release of...
... No, not really. Besides the problems mentioned by David and Reiner, Astrometrica is currently only distributed via download from the Astrometrica-web page....
... We are out of UCAC2 CDs, all 1000 copies have been distributed. If you know someone who has an original copy, please contact that person. If not, we still...
... V UCAC-2 Oups my mistake of course I was meaning UCAC-2 :-) ... Just to say that GSC 2.2 covers all sky for stars up to magnitude 18 (and there are some...
Also- I broke one of my 2UCAC discs, read that note, and emailed them anyway. My new discs arrived 5 days later.. But yes, the discs are copyright free and can...
