I do not know what percentage numbers Astrosynthesis uses for generating stars in a sector of space.
While working on my Stellar System Generator program, I found several science and university sites that listed the percentages for the Spectral Class of stars. I averaged them out and converted them into integer values. To do so, due to the small number of O class stars, I had to use 10,000,000 stars as the base. With 10,000,000 stars, below lists the number of each spectral class.
Spectral
Class Number
M 7,654,172
K 1,211,452
G 760,912
F 300,360
A 60,072
B 13,023
O 9
As said I do not know what Astrosynthesis uses, but I thought to post this to show what the actual numbers are for upcoming updates.
