COMMUNITY ADDON - Double/Multiple Asteroids fixes for SE

Thanks for update guys! I integrated the whole catalog, removing "Remove" objects manually from other catalog files. It will be in the next Steam update. Since now, please also add new objects to a separate sc file as "update for 0.990 patch 14", so I could track them and add manually.

Some errors (probably?)

Fixed Lempo discovery date, added alternate designations to all its components
Fixed discovery date of 2007 OR10 and its satellite, I also moved them to SolarSys.sc
Fixed many missing-slash names like this: "S2007 (1453) 1" -> "S|2007 (1453) 1"
Fixed a lot of syntax errors and missing parameters (for example, (5112) Kusaji have missing Mass value, a lot of asteroids have empty DiscMethod)
Asteroid "Siding Spring /(2343) Siding Spring" (with space before /) is renamed to "Siding Spring$AS/(2343) Siding Spring" ($AS are non-printable characters). Comet "Siding Spring/C|2013 A1 (Siding Spring)" is also renamed to Comet "Siding Spring$CO/C|2013 A1 (Siding Spring)".

I also added a code which reduces model radius of small asteroids, which are too "bumpy" and thus looks too large (significantly larger than selection pointer "radius"). Now small asteroids are more or less fit into provided mean radius. They became more round though...

But I meant for the asteroid '3122 Florence (1981 ET3)'. That's probably not in the ephemeris database at all.
And if it should be in, I do not know its parameters. (AnalyticModel, RotationModel)

Of course no, I didn't implemented ephemerides for asteroids.

Sure will do.
As you probably suspected, since the catalog is intended to be compatible also with 0980, that's the reason for missing slashes. Same reason for that space for (2343) Siding Spring, it's a "trick" in order to separate comet and asteroid in Object Finder in a pleasing way, without changing official definitions. For patch 14+ updates we'll use correct syntax (thanks, notepad++ macros! ;)) as well as the special character $ if needed.

The rest slipped through my checkings. v_v

That was indeed a visual discrepancy, great! We'll see how it goes.

Updated asteroid (809) Lundia: mass ratio and shape parameters from this article. This will work only in 0.990, because it supports tri-axial ellipsoid shape.

For 0.990, if you find dimensions data for asteroids, you can use them in catalog script. Note that dimensions are usually twice larger than radius: they are "diameters". In the Dimensions (X, Y, Z) parameter, X component is along orbital path, Y is rotation axis, Z is in direction of second companion. Usually Y is smallest, Z is largest.

To make asteroid shape more "round", reduce venusMagn: it is amplitude of the global "random shape" of the asteroid (and venusFreq is its frequency). This will work in the next patch (build 15).

Asteroid "Lundia/(809) Lundia"

   ParentBody   "Lundia system"

Hey Mosfet. I have been looking at the asteroids I have submitted and noticed that for most of them I gave incorrect axial-tilt data. I just thought you should know. Do you want me to remove the axial tilt data in the ones I provided?

Hey Silicon. Shouldn't be a big issue, you could just help me with the list of asteroids you provided, and I'll check them.
