CATKIN2.03

The code catkin is a simple two-body kinematics code, written in MS excel so as to be as portable as possible.

_Inverse kinematics_ case:

Note that in inverse kinematics, the complement of the catkin center of mass angle is correct center of mass angle for the reaction, e.g. to compare with reaction cross section calculations!
