Typbürste,
before I have a new computer I can not do much. This may take a while.

But I do not mind if someone else wants to try it.

My question is this: Extract a zip folder like AsBeCre-v0.3.1.py into which folder in the SE? Thank you.

You can extract 'AsBeCre-v0.3.1.py.zip' into any folder of your choice. I use a folder named 'Tools'.
If you have Python installed on your computer, you can run the file 'AsBeCre- v0.3.1.py' in this folder.
The asteroid file is then created in this folder.
You must then copy this file to 'addons\catalogs\planets'.

I wasn't sure how I may use either AsBeCre-v0.3.1.py (PY file) or AsterRingMaker.bat (Windows batch file) for making asteroid belts in the exosolar systems. No tutor on this yet. For one example: Epsilon Eridani has two asteroid belts and one confirmed exoplanet (AEgir or EPS Eri b) but with another unseen exoplanet (EPS Eri c). I exported two script files, EPS Eri for star and AEgir for planet to export folder in SE. I exported a gas giant from one of solar neighbor stars and created EPS Eri c script file out of that. Changed it to a ice giant and changed few atmospheric and orbital parameters according to Wikipedia information. AEgir revolves in very chaotic, steep orbit around the star at 3.50 AU, but EPS Eri c revolves in normal ecliptic orbit at 40.18 AU. Most asteroids are assumed to orbit in the ecliptic plane around the star like in our own solar system. I tested EPS Eri c script file by putting it in data\catalogs\planets and it works really great. I didn't use EPS Eri and AEgir script files yet. I have to figure out how to use asteroid belt maker.

I have made two asteroid belts for 'Eps Eri'.
But I do not know which 'Inclination' they must have. I gave them the same Inclination as the planet 'AEgir', but the orbit of the planet cuts the path of one belt. This seems me unlikely.

Thank you very much in advantage for your recent created asteroid belt scripts for Epsilon Eridani's two asteroid belts.
I have made two asteroid belts for 'Eps Eri'.
But I do not know which 'Inclination' they must have. I gave them the same Inclination as the planet 'AEgir', but the orbit of the planet cuts the path of one belt. This seems me unlikely.
  You are very correct in assuming that the orbital inclination of planet 'AEgir' is as same as that of the main asteroid belts. Hubble Space Telescope finds that orbit of AEgir at Epsilon Eridani is at same tilt as the star's circumstellar disk, 25 degrees- even though no inclination data was given in Wikipedia's Epsilon Eridani planetary system table.

In fact, the website of en.wikipedia.org/wiki/Epsilon_Eridani says about controversy nature of AEgir's orbital parameters:
"The frequently cited value of 0.7 for Epsilon Eridani b's eccentricity is inconsistent with the presence of the proposed asteroid belt at a distance of 3 A.U.  If the eccentricity was actually this high, the planet would pass through the asteroid belt (A) and clear it out within about ten thousand years. If the belt has existed longer than this period, which appears likely, it imposes an upper limit on Epsilon Eridani b's eccentricity of about 0.10-0.15."

Moreover, the website of http://www.solstation.com/stars/eps-erid.htm says more about this subject:
"Although some researchers previously suggested that 'Epsilon Eridani b' moves in an exaggerated ellipse ranging between 1 and 5 Astronomical Units around its host star, such an orbit could cross and quickly disrupt and 'clear out' the newly discovered innermost asteroid belt; hence, the Spitzer team of astronomers argues that planet b must have relatively circular orbit that keeps it just outside the inner asteroid belt, such as the eccentricity of e=0.25 +/-0.23 reported by Botieu et al in 2006."

Best solution for this problem is to change AEgir's orbital parameters and conform it with the inner asteroid belt.

Finally I found a way of how to make Epsilon Eridani's two exoplanets revolving in the same orbital plane of two main asteroid belts around the star: simply by changing their orbital parameters like eccentricity, inclination and ascending node. I was able to transform AEgir or Epsilon Eridani b's  highly elliptical orbit into nearly more circular orbit so it can revolve outside the Asteroid Belt A, and also Epsilon Eridani c revolve outside the Asteroid Belt B. However, I find that putting a programming line like Remove "AEgir/EPS Eri b"  {ParentBody "EPS Eri"} as the first in my script file AEgir.sc does not remove the original planet AEgir from the SE. So I have three planets listed in the Search box. NASA's James Webb Space Telescope will confirm those exoplanets in 2018. I have following files updated to accommodate new orbital data:

This is because in the 'ExoPlanets.sc' script 'Ran' is used as 'ParentBody' for AEgir.
(One of Eps Eri's alternative names)

Put 'Remove  "AEgir/EPS Eri b"  {ParentBody  "Ran"}' at the beginning of your script. Then it should work.

It worked very beautifully!! The search box now shows two planets. Thank you for showing me how I may correct the first line in my script files. I have also updated both AEgir.sc and EPS Eri c.sc with DiscMethod and DiscDate as the following:

Starlight Glimmer, Thank you very much and your welcome. I already have my own custom-build desktop with Windows 10 64-bit.

JackDole, Where would anyone post the suggestions about correcting the 'age' problem for Epsilon Eridani? SE 0.980 listed the star's age as that of "11.105 billion years" but Wikipedia actually lists its age as "720 million years" or 0.72 GA. This is because extremely old star systems do not possess dusty proplanetary disks (like outer Kuiper Belt) greater than 1-2 GA. Also, Wikipedia's physical inform for EPS Eri differs from that of SE. :)

I am on a planet and see this.

With a field of view of 75 degrees I see that.

How is the system constructed?
