The script file for Cirax addon already has them removed:

The file of Cirax has only the first three planets removed. SE 0.980_e already contains all seven planets. Therefore, all seven planets must be removed.

You only need the two scripts that I have posted.
RemTrapStar.sc (Put in 'addons\catalogs\stars')
RemDefTrap.sc (Put in 'addons\catalogs\planets')

Put them in the specified folders.
[hr]
If you want to change the original files of Cirax, paste this into 'TRAPPIST-1 planets Cirax.sc': And this in 'TRAPPIST-1 Cirax.sc' [hr]

The same applies to the star "2MASSW 23062-05022", since Cirax uses a 'StarBarycenter', not a 'Star' in the folder 'catalogs\stars'.

I expressed myself wrong here.
Cirax uses a 'StarBarycenter' named 'TRAPPIST-1 System'.
The name of the original 'StarBarycenter' is "2MASSW 23062-05022". That's why it needs to be removed.

Thanks! That got rid of the duplicate system!

I added the script line for removing the remaining planets (e,f,g,h). Go my new exoplanets thread here , download the Trappist-1 System and overwrite the old one.  I hope it works. (I don't have the "e" patch I was waiting for a major update).

I added the script line for removing the remaining planets (e,f,g,h).

Your changes remove all duplicate planets, but not the second star. This line is missing in the planet script: And in the star script this line:

*hits download button really hard*
Yes, this needs to exist and I'm glad I don't have to be the one to make it.

 Now works with 0.978e patch, I just added the code.  Thanks.
