Could someone please provide an addon/.stc where Antares, Betelgeuse, the Ruby Star (=119 Tau), P Cygni, R Lep, T Cephei (=HIP 104451) and Rho Cassiopeiae have their radii modified to correction? I have tried to make my own addon/.stc file but it would not work.

Antares: 883 solar radii (https://simple.wikipedia.org/wiki/Antares)
Betelgeuse: anywhere between 887 + 203 to 1,180 solar radii (https://simple.wikipedia.org/wiki/Betelgeuse, https://en.wikipedia.org/wiki/Betelgeuse)
The Ruby Star: 608 solar radii (http://www.newforestobservatory.com/2012/07/02/th ... in-the-sky-119-tauri-ce-tauri/)
P Cygni: 77 solar radii (https://jumk.de/astronomie/big-stars/p-cygni.shtml)
R Lep: 500 solar radii
T Cephei: 540 solar radii (http://vizier.u-strasbg.fr/viz-bin/VizieR-5?-out. ... ource=II/224/cadars&recno=9837)
Rho Cassiopeiae: 450 solar radii (https://jumk.de/astronomie/big-stars/rho-cassiopeiae.shtml)

Thank you. - Joey P.

What format did you use for your .stc catalog?
If you can provide an example, someone might be able to point out your mistakes.

The file /data/charm2.stc includes updated radii for many stars, thus providing valid examples of how to change them. As another example, here's an stc which changes the radius of Antares.

also i hope you are NOT using Microsoft word to do this

it will not work

use SciTe or the scite based editor "notepad++"

http://www.scintilla.org/

https://notepad-plus-plus.org/

then there is always Emacs ( there is a windows build )
-- one of the BEST in the world --
https://www.gnu.org/software/emacs/

An extra note to be careful of.

You also need to be sure your editor is in Ansi/Ascii mode, not utf-8 because the parser in Celestia has issues with MBCS in ini/cfg/ssc/sst/data files.

Notepad++ defaults to UTF-8 on import unless you set it otherwise because it is internationalization friendly that way.
I changed the source of mine and recompiled to force it Ansi/Ascii unless I select otherwise.

Just don't want to see anyone else get stuck in the same rabbit hole I did.
You can easily check for out of bounds characters using ztree viewing in hex mode.
The quickest check is to look for characters with values $80(0x80) and above.

Thank you. Here is my addon, for download: https://drive.google.com/file/d/1Pax5rZpmyN_FMXiDEbF2wfS4k2hhtY8A/view?usp=sharing

BTW, Antares is now r=557,000,000 km

I am using notepad .

Using notepad doubtless is part of the problem. It doesn't provide enough control over the editing process. As John suggests, install and use Notepad++ instead.
