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!

Hello world, this is Stelle Doppie release 1.4
It's a long time I don't post here.
I promised to myself to release a new version until I fixed orbits calculation forever, but too many months passed by, new features were added, big improvements were made and I could not wait anymore. I'll continue to work on orbits for the next release.
As always, let me know if you find something wrong.
[fix] large orbital periods had errors in calculating sep_now. Dates where not
displayed in years. This is yet to be fully verified.
[fix] some lists where not related to a username and I was forced to delete
them. I'm still investigating what happened.
If you can't find some lists you created, you know why.
[fix] labels of dates in orbit graph are now visible
[new] !!! added virtual eyepiece inside Images tab as you select a double
This is a feature I was dreaming for two years but never had time to
implement it. Have fun, as I do!
[upd] complete lower-level rewrite due to upgrading to newer database library
[fix] fixed mag_sec = 0, void and not void searches
[mod] better search in left box. Now discov_num is recognized (i.e. STF,
STRUVE, ...) and a generic search is not performed
[mod] updated Catalogs Help menu
[mod] updated Credits in Help menu
[new] My Catalog in Contributes (!) to search your own references in WDS notes.
To support this feature, a new field for the assigned discoverer code
was added in Setup->Preferences
Free you ego!
[mod] My Lists also available as a menu in Contributes
[new] Users' Lists added in Contributes. You can enable to display your
list using Shared checkbox in your lists setup. You can disable
an other user's list to be displayed clicking the Option link,
then click the Hide checkbox.
Because your list names can became public, lists flag where modified
to be NOT Shared. If you want to share a list, from this time on it's
your choice. Please don't abuse or YOU'LL BE DELETED FROM THIS SITE.
I have not time to moderate. No flames, no discussion, no comments,
no stupid things at all. I trust your common sense.
[upd] code maintenance to clear language's deprecated functions
[new] a new filter in Catalogs to select Main Double only (AB)
[fix] flag "primaries only" in Neirborhoods now working as planned
[mod] in Neirborhoods, raised Limit from 50 to 100
[mod] in Advances Search, raised the Radius limit from 8 to 30°
[mod] standarized sequence in lists: ra,dec ; rho,theta ; sep,pa
[mod] reorganized double star WDS data to render things more clear

I'm not worthy. Thanks for the site. I see I can use the SAO numbers, since my scope can use them for finding these star systems easier. Celeston does have double stars in the computer but not too many and not too hard to resolve.

The DS community is in your debt. Thank you for continuing development of this excellent tool!
