Revised numberedmoons.ssc

Post #1by **granthutchison** » 10.02.2004, 11:32

JPL have published revised ephemerides for the mass of Jovian moons discovered in 2003 - quite significant changes to distances and eccentricities in many instances. They've also just produced official data for 2003 J22 and 2003 J23. I've incorporated these changes and additions in numberedmoons.ssc, available from the CVS tree at http://cvs.sourceforge.net/viewcvs.py/celestia/celestia/extras/numberedmoons.ssc.

Hey,

Thanks Grant... Don't you have a life either? :lol:

Got the ssc, and thanks again.

However, when I simply right-clicked on the link and chose "Save Target As" what I got was a strange HTML-type text file. Is this the correct link?

The following is a sample of the file I got:

Code: Select all

After I opened the link in a new window, I was able to download the SSC file from there. Just thought I'd let you (and others) know about it.

Take care, Bob

Grant,
I'm currently running Jacks "JACKtiny_or_new_moons" ssc.

Can the new "numberedmoons" be used as a direct replacement ?

regards
TERRIER

Yeah, minormoons.ssc and numberedmoons.ssc between them cover all the moons in the solar system for which JPL provide ephemerides: there are usually a couple of moons knocking around that have recently been discovered but don't have tight orbits calculated yet, so they aren't included. At present, we're missing two new Uranians from last year, and the rediscovered Uranian from 1986. I know Jack provides elements for the 1986 moon in his file, but it's unlikely to be accurate since the thing went missing for 17 years - I'm waiting for the JPL update before I include it.

Just finished converting it over
big changes to the Jupiter un-named moons

Thanks Grant

It's a link to the relevant page of the CVS tree. From there you can download the file with a right-click on the "Download" option. What you did was download the HTML for the CVS webpage.

What Grant said!

I think I might discontinue my tiny_moons file actually, since numberedmoons.ssc is actually updated, and I haven't got the time at the moment... However, I really hate the format numberedmoons comes in, with the | character splitting the lines- it makes it incredibly hard to read! Grant, is it possible to change this so it looks a little more like the way I had my tiny_moons file laid out?

Thanks!

What kind of editor are you opening it in? It's just built in Notepad and laid out the same way that solarsys.ssc is laid out, with a standard Windows CR/LF at the end of each line, instead of the Linux plain LF.

I have a similar 'problem' when viewing it using Notepad. All the text is in one big lump, with each new item seperated by a square.

I have word wrap on, page size A4, source 'automatic', if this makes a difference ?

When Notepad displays a text file as a single lump containing squares, that means that the file has been stored on the Windows system with only line-feeds for line terminators.

This happens because the file is being provided by the Web server in standard Unix text format, but the Windows browser doesn't realize an SSC file actually is a text file. As a result, the browser's download process doesn't insert the carriage-returns that Windows normally uses.

If you read the file with WordPad, it'll look OK.
If you then save the file from WordPad, "Carriage-Returns" will be added and the resulting file will look fine in Notepad.

Trinculo's diameter is given as 10 km in http://www.ifa.hawaii.edu/~sheppard/satellites/urasatdata.html
I compared the sizes of some major moons to those given on the Nine Planets site and found that it's the diameter that is given. So the radius in the numbered moons ssc file should be given as 5, not 10. Now I'm the one who needs a life. :lol:

Ah! Thanks- i'll give that a whirl so and see how it works out.

Good spot, thanks. I've fixed it. Not sure how it happened, since I generally use JPL as my reference site, and they do give the radius as 5.
