When asking that question, you were not even aware who had done all that work about the binary orbits ;-)

Nonsense. I was well aware of who had done all the work on the binary orbits. That wasn't the question. The question was who would do the remaining work necessary to fix the problems noted by Cham.

Fridger, I may have found a simple and elegant solution :

Just add the suffix "AB" to all barycenters which only has an HIP name, like this :

Code: Select all

 Barycenter "HIP 2237 AB"


That way, we could select the barycenter using the command line, and it's also working great with a script.

That suffix also shows clearly to the user it's about a barycenter.

Cham wrote:Well then, the problem is to avoid the ones you have indicated in a previous message, and that I've indicated too :

In a given binary, how can we select the barycenter itself from the command line, if it has the same HIP name as one of the components, as stored in Celestia's internal number ? This is also causing some selection problems with scripts.
Right now I think the fact that for binaries without proper name one cannot dial the barycenter is simply a bug. If I find time or if Chris L. finds some time, this should be an easy matter to clear up.

If the barycenter can't have an HIP number in front of its name (in the STC file), is it a good solution to simply remove the HIP number in front of the star names, since Celestia can identify the stars from their declared names anyay ?


Well the multitude of possibilities to writing a name is a real problem here. A (HIP) number is a much cleaner way of identification. With PERL I can simply chop off anything but the numerals and then I know what the object is, INDEPENDENT of syntactical issues! You see, my PERL scripts already do quite sophisticated things:

First of all, I read in the entire stars.txt file of Celestia and merge it with the actual correction file, revised.stc. After some consistency tests, I use the RA, DEC and distance values from the main Celestia star database for the coordinates of the binary's barycenter, in order not to encounter some slightly different values in the display! This is just one of various actions. Without using the HIP numbers this would be virtually impossible...

From my extended tests it seems the overall situation is not all that bad. But we do need to do some adaptations in the code to become conform with the "standards". I don't think the effort would be very high. But it's clearly more than just writing posts with proverbs... ;-)

Fridger,

please read my previous message (if you haven't already, since we're cross-posting). What do you think to just add "AB" to the barycenter's name (with an HIP name only) ? This is solving all issues.

Indeed, Cham, that seems to work!!

However one has to also write

OrbitBarycenter "HIP 2237 AB"

So here is a concrete test case in visualbins.stc:

Code: Select all

 Barycenter "HIP 2237 AB"
 {
 RA         7.088207
 Dec      -20.334776
 Distance 105.181230
 }

 
 2237 "HIP 2237 A" # component A
 {
 OrbitBarycenter "HIP 2237 AB"
 SpectralType "G3V"
 AppMag  7.27
 
        EllipticalOrbit {
                Period               5.650
                SemiMajorAxis        2.205 # mass ratio 1.29 : 1.32
                Eccentricity         0.660
                Inclination         62.698
                AscendingNode      197.148
                ArgOfPericenter    235.834
                MeanAnomaly         15.929
        }
 }

 "HIP 2237 B" # component B
 {
 OrbitBarycenter "HIP 2237 AB"
 SpectralType "?"
 AppMag 7.35
 
        EllipticalOrbit {
                Period               5.650
                SemiMajorAxis        2.162 # mass ratio 1.29 : 1.32
                Eccentricity         0.660
                Inclination         62.698
                AscendingNode      197.148
                ArgOfPericenter     55.834
                MeanAnomaly         15.929
        }
 }


Do you agree?

Yes, and to any insider it was obvious that only me could to that stuff properly...

Yes, of course I agree ! :wink:

This is also what I've done in my pulsar binaries addon.

Perhaps it was obvious to you. But for others that might depend on the definition of "properly". And others could not assume that you would be willing to do it, even if you were the only one who could do it "properly".

Martin,
do you want me to quickly generate and post the correspondingly modified visualbins.stc and spectbins.stc files for further testing?

Yes, please.

And I'm sure we're getting to the final version now, most probably ready for CVS and mass consumption ! :D

This is getting increasingly bizarre. Did you really think that after 6 years of continuous engagement for Celestia I just "sneak out" of development like that?? ;-) This really sounds a bit naive.

Ask anyone around here who knows the scene...

Actually we havn't seen all that much of you during the past year until very recently? What has changed?

Hi all,

please have a look at my next iteration of visualbins.stc & spectbins.stc:

Here are again the download URL's:

the modified PERL scripts

http://www.celestiaproject.net/~t00fri/images/ ... ins.pl.zip
http://www.celestiaproject.net/~t00fri/images/spectbins.pl.zip

and generated .stc files for download and testing:

http://www.celestiaproject.net/~t00fri/images/visualbins.stc
http://www.celestiaproject.net/~t00fri/images/spectbins.stc

The changes were minute, following Cham's suggestion:

Code: Select all

$alt{$hipnmb,'AB'} = $cross ne ""?"$cross"  :"HIP $hipnmb AB";


This should allow to dial the barycenter in cases where the binaries only have a HIP number (and not a proper name)

Thanks a lot Fridger.

I've tested the new version. Everything appears to be fine now. I think it's ready to be commited on CVS.

And here's my modified script to mark all these binaries. In blue : visual binaries (excluding Grant's binaries). In orange : the spectroscopic binaries, in green : other binaries (from Grant). This script includes ElChristou's suggestion to give a feedback to the user.

Code: Select all

# Title: Marks the barycenter of 239 star binaries.

Martin,

many thanks, the script looks nice. However there is one binary that is FAR out of the MilkyWay?! Typo? Or real?

Far out ? You mean above the galactic plane ?

There's a pulsar (with a white dwarf, if I remember) located in M4 (globular cluster). This is "PSR 1620-26:PSR B1620-26:PSR J1623-2631". There's also an exoplanet around it.

This binary comes from Grant's "extrasolar.stc". In the script, it's an element of the "56 other binaries", near the end of the script.

Maybe I should give'em another color ?

Yes, that was it. Sorry I only know "my own babies" ;-)

So I'll just wait to hear Chris L.'s opinion and then I will commit it to CVS.

Thanks for your creativity!

Ask anyone around here who knows the scene...
Fridger, the problem is that you have a tendency to use your contribution to Celestia as a blunt instrument when you're upset with someone.

[examples edited out]

So regrettably, there's some reason for concern about your continued participation in Celestia.

My outburst was prompted by the review of Seeker3D in S&T that didn't even mention Celestia, contrasted with the continuing delay in releasing 1.5.0 and the consequent dissipation and fragmentation of the Celestia community.

It was a pleasure ! :D

I've updated my previous script to change the color of the "other binaries".

yes, Hank, I have admitted in public that I was/am upset about the fact that Chris L. let ALL his old collaborators hang around here for 3 months without sending even a little mail of what was going on. ... let alone the fact that Celestia development came to a total halt.

In my (professional) environment NOONE lets me hang around for three months, believe me ;-) .

So, what's next? ;-)

I am playing in parallel with improving the hires Saturn rings. That's also a nice physics problem to get BOTH the trasmissivity AND the albedo right.
