Needless to say, I'm really excited to work on KStars this summer :) I am relatively new to the community, so I'll take a moment to introduce myself. I'm Rishab Arora (idling on IRC as 'spacetime'), an undergraduate student of Information Technology from New Delhi, India. Currently in my third year of college, I take particular interest in handling large amounts of data. I'm an amateur astronomer and have a habit of naming devices, heuristics and algorithms (or anything I can name) after heavenly bodies, so I think I should fit right in. ;) I'll start with a small description of what I've be aiming for this summer. My proposal "Improving Data Storage, Logs and adding DSO catalogs to KStars" involves a. building a log viewer which will enable users to 'store' observation logs in an internal database b. improving the way data files handled, specifically the parsing of text files.

My project proposal for Google Summer of Code, 2012, with the idea - "Make KStars more usable for beginner astronomers by adding 'What's Interesting...' feature to KStars and by making 'Star Hopping' feature user-configurable" - has been accepted. It is really exciting and I am confident that this would be a rewarding experience for me, the community and the users of KStars. Through these features KStars will become more friendly and usable for beginner and intermediate level astronomers. Anyway, even though I am not new to this list and have posted here in the past, I would like to introduce myself here in brief. I am an undergraduate student of Computer Science and Engineering at National Institute of Technology in Durgapur, India. I have made contributions to KStars as a part of Season of KDE, 2011 and afterwards. To know more about me, my project proposal and previous work you can take a look at my blog at http://samxan.wordpress.com/ .

Looking through the code, I can't tell why this is happening. I ran a check on my catalog for incorrect magnitude order, but the tester (data/tools/nomadbinfiletester) reported no errors. This was very likely introduced after Akademy 2008 (August 2008), because I'm almost certain that I weeded out most of the bugs before that, and something like this would have almost certainly caught my attention. However, these bugs are also hard to find because they could happen only for specific regions of the sky. In this case, the output on my terminal shows this happening for trixels 32606 and 32607 which seem to lie around M 34 in Perseus. Alexey introduced some changes in this code, but looking through them, I d</pre> Akarsh Simha 2012-04-18T07:46:24 http://comments.gmane.org/gmane.comp.kde.devel.kstars/4575 <pre>The USNO NOMAD catalog seems to have artefacts near bright stars. I'm guessing that these owe their existence to diffraction spikes and glare, as is seen in the POSS plates. AFAIK, NOMAD uses the POSS plates to find stars. For comparison, consider the query on NOMAD here: http://www.nofs.navy.mil/tmp/fchTdJ3EC_fch.html The same field, with the same central star in the POSS [Blue] plates: http://archive.stsci.edu/cgi-bin/dss_search?v=poss2ukstu_blue&amp;r=18+12+24&amp;d=-07+17+44&amp;e=J2000&amp;h=15.0&amp;w=15.0&amp;f=gif Notice how some stars are spurious and some magnitudes are over-estimated in NOMAD, possibly due to the diffraction spikes. The same artefacts are found in KStars -- all bright stars usually have a string of stars flanking them, that are usually aligned approximately with the north-south direction. I guess these artefacts are the result of diffraction spikes. It is therefore unlikely that these disagreements with DSS images are bugs in KStars -- they are more likely catalog artefacts. Regards Akarsh </pre> Akarsh Simha 2012-04-15T21:22:47 http://comments.gmane.org/gmane.comp.kde.devel.kstars/4568 <pre>Hi I did some tests on the USNO NOMAD catalog machinery in KStars today. I'm sending a copy of these to the mailing list both for documentation / archival purposes and so that others can look it up when required. This was prompted because I noticed that the star field in Trixel 12310 (of the "deep" level 6 SkyMesh) did not seem to match with the DSS image of the same region. This could involve precession and might be related / a bug introduced by the short-circuiting of precession, nutation and aberration computations when the simulation time elapsed since the last such calculation is less than about a minute (see revision 832469e64f222e6d1cc9da77a7b4587db20c05ba). Or it could just be that the catalog (with the search criteria used to limit down to a 100 million stars in KStars) disagrees with the POSS plates. The following are the results of some checks done against trixel 12310 / a rectangular patch in (RA, Dec) around trixel 12310: 1.

Committed on 14/04/2012 at 13:50. Pushed by asimha into branch 'master'. Lots of changes that were tightly coupled: 1. Reorganize options related to Observing List in kstars.kcfg under a new group. 2. Revamp the design of the "Advanced" options section to introduce a Tab Widget [I need feedback on this decision]. This is so that we can put all the advanced options in there without any clutter. [Q: Does observing list belong there?] 3. Remove the hackish DSS vs. SDSS preference option in the Observing List view and introduce the setting in the Advanced options under Observing List.

This is that part of the timeline when the Google distributes its limited slots to open source projects, and large open source projects distribute those even more limited precious slots to various proposals in KDE. While students owe their "allegiance" only to the project and their summer job, mentors have to see the interest of both KDE and the open source community at large, and the students at the same time. It's hard to be completely fair to one party without doing some injustice to the other. That's part of the reason I usually recommend that students apply to multiple projects (despite that not being in the interest of the organization), because you shouldn't lose out just because of other factors. Let us hope that all turns out well at the end of the day, but I'm just writing this to prepare us all in advance and point out to you that if we didn't pick you, it doesn't mean that you weren't good enough to do a GSoC.

I'm considering applying for GSoC this year and had the following idea in mind. I thought I'll share it with everyone and ask for their opinion. Inspiration: A few weeks ago, I was with a local amateur astronomers group and we were discussing the recent mars opposition. To explain some things, we needed a way to visualize the earth from above the sun and see how the March opposition is as distant as it could be. And I realized that this could be a feature for kstars. What I wish to implement: Using the openGL backend, a way for the user to observe stars and planets from: 1) Different elevations of the earth. 2) From the surface of any other planet 3) From any point hovering in space (not bound to any planet) Also, this would let me add another feature: split-screen mode In split-screen mode, the user can view the universe from multiple viewpoints at the same time. For eg. One could see the said mars opposition hovering above the sun while watching it simultaneously located on earth. So?
