Add-ons

[Askaniy]

TrueColorTools supports add-ons (extra spectral data) to be placed into the spectra_extras folder.
This is useful for expanding the database with heavy spectra or data from low quality sources.
I recommend organizing users' add-ons by creating and updating comments with lists, one comment per author.

"Official" add-ons:

• CALSPEC database (100 high quality stellar spectra);
• HAZMAT synthetic spectra of GJ 176, GJ 436, GJ 832 and TRAPPIST-1;
• 87 spectra of PSR J1023+0038 within 1.1 hour by Messa et al. 2024.
