Hello,
I attach an STX file. The list contains the stars of special spectral characteristics that Angelo Secchi submitted to the French Academie des Sciences in 1868.
Secchi investigated the stars contained in Schjellerup's Catalogue of Red Stars and found these 16 stars (a 17th star is not clearly identified) to be markedly different from all others. Today we know them as carbon stars.
The rating is based on Secchi's aesthetic evaluation.
