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:
