This implementation of the TOF correction tool implements a simple correction using a straight line hypothesis and assuming particles to move at the speed of light. This leads to known overcorrections, and has to be refined in future implementations of this tool.

FIXME:

• impact parameter resolution has yet to be propagated to TOF_error!!
• faster sqrt?? e.g. float sqrt2(const float n) { union {int i; float f;} u; u.i = 0x1FB5AD00 + ((int)&n >> 1); u.f = n / u.f + u.f; return n / u.f + u.f * 0.25f;}
