Double Stars Database
Posted 22 September 2012 - 02:06 PM
You've done a fantastic job with that site, Gianluca. I find myself reluctant to switch over to the WDS now unless I need to confirm some data or search for something not otherwise available.
Very, very much appreciated, believe me!
And the Bulletin of Double Stars looks very appealing as well -- I'm working my way through that now.
(P.S. -- just sent you a PM, also)

I advice you all there is a bug in the "advanced search" page: I tested searching for SAO, it seems to have no effect. Still investigating.
When checking the visual filter flag the algorithm did not filtered doubles with magnitudes out of resolution limit of the telescope. This was fixed but not yet in production.
I also discovered an unexpected format of the Orbit 6 catalog, confirmed by Dr Mason, USNO. Some data are duplicated for the same double because the are multiple solutions to the orbit. Difference is most cases minimal, it's matter of decimals, but I had to invent a solution to handle this. So it may happen multiple graphs are displayed, and "pa now" and "sep now" refers to the first graph.

I just updated the WDS to nov 17, 2012 release.

Thanks for keeping that site going, Ginaluca!

I'm getting a 403 error when I try to go to the registration page. Using Firefox 19.0.2 and IE9.
I've tried the registration links from these two pages:
Both return the 403

It's time to consider the stelledoppie.goaction.it website stable, so I passed it to version 1.0.
Here is a short list of updates and bug fixes.
[new] flamsteed shows number and constellation, not only the number, ie 30 boo vs 30.
[new] news ordered descendant by date
[fix] table fix in orbital elements
[fix] an .htaccess problem prevented new registrations and login/logouts
[new] implemented References and Authors in Notes, a new database file imported by the WDS website
[new] implemented "between" and "not between" to work in searches, using a comma to separate terms
[fix] in neirborhood graph coordinates were inverted left-right. I know there's more work to be done here.
[new] in advanced search, added date first and date last fields
[new] in advanced search, added notes flags field, the one in the main WDS file.
[new] the WDS import script was redesigned to minimize lost records (doubles that changed designation)
[new] constellation (cst) column in lists
I planned to implement a coord to clipboard feature but I realized it's a time-consuming task, so I solved modifying the coord_arcsec_2000 field layout leaving out the grade symbols to permit cut&paste without strange characters to be deal with.
In the next release you'll be able to merge, integrate and do many operations on you personal observation lists. Export to SkySafari too... if they will kindly import the entire WDS in their software!
I know there are many bugs to be fixed.
It's all for now.

A bug was fixed that prevented to display the correct value for rho and theta in sep_now and pa_now when an orbital solution was found.

Thank you to Robert and Gianluca (not me!) for their bug reports.
[new] added Tycho-2 in simple Search box. BEWARE: this is experimental, I know some records are off.
[mod] left menu changed in Catalogs, added "Computed Lists" and "My Lists"
[new] "Doubles seen" list back online (requires login)
[new] Besselian and Julian dates calculated in measures and reports
[new] list export to SkySafari (!!!)
[fix] pa_now,sep_now calc fixed when Orbit6 was involved (7 Tau was 0.54" sep instead of 0.7")
[mod] Double star WDS data listed in 4 columns instead of 3 to improve reading
[fix] could not modify or delete reports and measures
There are many people using custom lists. I'll improve this area in next version. You'll be able to merge lists (union, intersect, difference) and import from different sources (yes, SkySafari too).

How do I export a list to SkySafari? I can do an advanced search but I cannot find how to export that search to a list (I think I did this one but for the life of me cannot figure out how again) and then where to click to export the list out...

You have to create a custom list in Setup->Lists :: New list
then enter in a double and add to the list using "Add to list" on the left.
Then return to Setup->List, click "Show" in My List, and "Export to SkySafari" appears on the left column under Actions.
I know, it's a weird procedure. I'm redesigning the entire list handler.

[mod] in advanced search, field boxes are of different sizes
[fix] a permission bug prevented a published report to be displayed to other users
[fix] fixed doubles seen in this section
[new] in Setup->Lists, now lists can be merged to create complex unions
[new] computed lists and searches can now be salved as a list
[fix] it was not possible to modify a report, and some fields could not be saved
[fix] in neirbourhood tab, a mouseover a red dot star shows again a comment
[mod] remarks field added to lists; description was renamed in title
[fix] fixed bad Orbit6 import, some values where truncated
[new] export to SkySafari for searches, user lists and computed lists (as requested by Roberto)

I'm Alan MacRobert at Sky & Telescope. I'l love to use one of your drawings of 44 Boo in the July 2014 S&T. Can you please email me, at macrobert@SkyandTelescope.com ? Thanks!
