Hi, I doubt that you will find any comprehensive and ready to use bibtex files which are at least halfways up to date. However, you may create them at your own by using the ADS abstract service at http://adswww.harvard.edu Follow the links `Abstracts' -> `Astronomy and Astrophysics Abstract Service' to a query form where you can specify authors, title words, text keywords and a lot more. On the bottom of the query results' page you can select `Return BIBTEX reference list' and then say `Retrieve all references' -- that's it. The only thing that perhaps remains to do is to adapt the original labels to your personal needs. BTW: a search for the keywords `cosmic' && `ray' yielded 8112 hits! Hope that helps.

The ADS allows you to search the astronomical literature (as well as literature on Astronomic Instrumentation). The Astronomy database contains over 400,000 references, the Instrumentation database over 500,000). The returned references contain links to a number of other information providers (eg. on-line journals, data centers, object databases, scanned journal articles). This service is a NASA funded project, and access is free world-wide. We have mirror sites in France and Japan to improve access times for non-US users. I am currently discussing another mirror site in Chile.

Scott Birney (1991, Cambridge University Press) gives a fairly complete guide to the reduction of radial velocities on pages 216-223. This is a good undergraduate level text in general, although primarily aimed at optical observations. Also, I think any edition of the Astronomical Almanac (a US Naval Observatory/HMSO publication) will give the equations you need, plus all the constants, but I don't have a copy to hand to check. Good luck, and do continue to publish your results!

What about the motion of the Sun with respect to the LSR or the LSR with respect to the Galaxy or... Even leaving those aside, the question is not so simple. You have to specify what level of precision you want, in order to know what sorts of approximations will be acceptable (and you probably want to use all the approximations you can). For example, the rotational velocity on the Earth's surface is less than .5 km/s -- if you don't need the velocity to that level, you can ignore the rotation entirely. -- John F.

Brad, There is a program in IDL and miriad called clfind that does this. It originates from J. Williams at CfA I believe, who documents the program at http://cfa-www.harvard.edu/~jpw/clfind.html. I think you need to get the BIMA version of miriad from http://bima.astro.umd.edu/bima/programmer.html rather than the ATNF version. Also, check with the Parkes multibeam guys (eg Lister) as they must be doing something similar to find the dwarfs in their data.

I don't know whether this fits your needs in galaxy detection. Gaussclumps was described in detail by Stutzki & Guesten 1990,=20 ApJ 356, 513. The code with some explanations is available by anonymous ftp at zeus.ph1.uni-koeln.de/pub/gaussclumps .

Vizier has a huge number of catalogs, but I If you have access to ESO/MIDAS you will find it can do that on MIDAS tables, but you have to import the data first. The Starlink CURSA package can do something similar, and will work directly on FITS tables. If I remember rightly, however, VIZIER will only export FITS ASCII tables, which makes the computations very inefficient. Perhaps converting to FITS binary tables would be a useful step. One could use FTOOLS to do that. -- -- Clive Page, Dept of Physics & Astronomy, University of Leicester.
