shift from sympa@astro to mailman at adjani

Witam, To make less work for Andrzej M in managing sympa on newton, and also as he and i discussed initially (a looong time ago), i've started shifting the mailing lists to adjani. So for the moment please use: cosmo-torun at adjani.astro.uni.torun.pl or use the alias cosmo-torun at cosmo.torun.pl The cosmo.torun.pl alias should also work for the adjani www pages - the general domain names we use here really are quite ridiculously long IMHO. i thought that cosmo.pl would be a bit too pretentious - but hopefully we have enough cooperation between CAMK and CA-UMK that we can together use cosmo.torun.pl. :) i've automatically described people who were on cosmo-torun at astro to cosmo-torun at adjani - but i haven't (yet) shifted the other lists. IMHO it is also worth thinking of what the best way of having lists is - the aim is to that we have good communication and are motivated by what each other is doing, and that on useful subjects it is easy to find info, but at the same time to avoid spamming. So far, i haven't really used any lists for much real work on a project, even though that was my idea. i realise that these were dictatorial decisions - but my feeling is that people are probably more concerned about decisions on scientific content, or for the undergrad students, decisions on course organisation and exams. Any thoughts, please comment. (Nothing about bramki on these lists, though. ;) pozdr boud

the WMAP pixelisation algebra is free now :)

Witam, Just one day before our deadline of 22 Sep, in response to our paper, the HEALPix people submitted a paper inspired by our work: http://de.arxiv.org/abs/astro-ph/0409513 So here's our version: http://de.arxiv.org/abs/astro-ph/0409547 The algebra is free (as in speech) now :). pozdr boud LISTNAME: cosmo-torun HELP: send an email to sympa(a)astro.uni.torun.pl with "help" WEB ARCHIVE: http://www.astro.uni.torun.pl/sympa/cosmo-torun/ UNSUBSCRIBE: email to sympa(a)astro.uni.torun.pl with "unsubscribe cosmo-torun"

For me it would be fine to have the paper in two parts: (1) the algebra of the pixelisation system (2) testing of numerical precision of the HEALPix software but let's hear what Bartek thinks. i should make it clear, to avoid any misunderstandings, that Kris and i have different points of view on different levels of freedom in software licencing issues (GNU GPL versus what Debian terms "non-free" licences), but IMHO there is no reason for this to be a problem with having both (1) and (2) in our paper. (1) The algebra is independent of any software at all, and (2) while personally i prefer GNU GPL, there are a huge number of cosmologists using the software under its present licence and it is clearly in their interests to be aware of numerical precision tests that have been done. Since you've done the work, and it's useful, it should be published. And there's no need to unnecessarily multiply the number of articles published (even if that helps with job committees, but i have a job now :). In that case we'll need a new title. How about something like this? "An algebraic derivation of the healpix pixelisation scheme and numerical precision of the HEALPix software" This way it clearly says that one bit is algebra, independent of any software, and the other bit is hands-on software stuff, useful to users of the software. Any better suggestions? We haven't heard back from any of the other people who seem to be "official" HEALPix collaborators (i didn't contact Tony Banday directly, because he requested not to receive emails from me - if you wish to contact him, please feel free to do so). Bartek: do you have any comments on including Frode's work in our paper?

Dear colleagues, Please find attached the draft of a paper of which we invite you to be co-authors. It is felt that the most consensual way to publish this paper would be to include the members of the HEALPix collaboration. We would be most happy to include your names as co-authors, if that is what you wish. However, if we hear nothing from you by Wednesday 22 September, then we will assume that you do not wish to be co-authors.
