In general, given two or more stars, then their singular combined magnitude value (M) can be found from the general summation given below.

Let:

N = Total number of stars in group.

m_n = Magnitude of n_th star in the group.

M = Magnitude of all N stars combined into one.

The general equation used within the program to
compute the N combined stellar magnitudes is:
