Source of the magic constants?

Oyster/Oyster.py

Lines 139 to 140 in a8e5749

	c1 = 0.1134141984932795312503328847998
	c2 = 2.8623043756241389436528021745239

I see that there are several magic constants used in this script. I’m trying to understand the specific behavior of this implementation, so can you explain what these constants are and specifically how they were calculated?
