Here a a table for those who don't like maths. Just match up your source code number using the steps above and then choose the moon number that corresponds with your source code number:
0 - 11.24 = 9
11.25 - 33.74 = 10
33.75 - 56.24 = 11
56.25 - 78.74 = 12
78.75 - 101.24 = 13
101.25 - 123.74 = 14
123.75 - 146.24 = 15
146.25 - 168.74 = 16
168.75 - 191.24 = 1
191.25 - 213.74 = 2
213.75 - 236.24 = 3
236.25 - 258.74 = 4
258.75 - 281.24 = 5
281.25 - 303.74 = 6
303.75 - 326.24 = 7
326.25 - 348.74 = 8
348.75 - 360 = 9
