<!--
   From the source for slip_skid_ball.cxx, the number returned is (-z_accel/y_accel)*10.
   For small theta, theta~=tan(theta) when theta is in radians.  So the angle of a "ball" 
   undergoing z_accel and y_accel hung on the end of a string makes with the verticle
   will be approximately -z_accel/y_accel radians. Converting to degrees, multiply by
   180/pi=57.29, or 5.729 times the returned value. Edited by Dave Perry, 2/26/06.
