[ElPelado]

I need to make a globular cluster using the Globular Cluster Generator.
it should be almost a perfect sphere.
what should i put in:
R +/-
D +/-
d +/-
Core

can some one help me??

By trial and error you can use those elements to produce various sizes of clusters. Use increments of +/- 0.1 to start off.

Core is a dispersion variable of the center stars within the core. R is RA +/- D is Dec +/- and d is distance from Sol +/- all in thickness relative to the center.
