Rocket FM?

[RedTracer]

Does anbody know what figures cx_coeff mean in file GRAD_9M22U.lua?

_G["weapons_table"]["weapons"]["nurs"]["GRAD_9M22U"] = {
	_unique_resource_name = "weapons.nurs.GRAD_9M22U",
	client = {
		fm = {
			...
			cx_coeff = { 1, 0.66, 0.49, 0.2, 1.53 },
			...
		},

They are so big. I've tried to figure out Cx in game by measuring breaking acceleration and what i found out:

V1 (start speed) 704,1672 V2 (end speed) 694,445 Delta speed 9,72223 t (time diff) 0,33875 a acceleration 28,70031 m mass 46     S square 0,014884     Ro (air density) 1,201 V (speed) 699,3061 Q, Pa (air pressure) 293661,9 F (breaking force) 1320,214     Cx 0,30204

It seems like true, because if I put this value in ballistic calculator I get almost the correct range of fire.
