+ SUBROUTINE GKHITS (IUSET,IUDET,EPSILO)
+C.
+C. ******************************************************************
+C. * *
+C. * Prints the hit picked (using the graphics cursor) *
+C. * from all the hits of all tracks in detector IUDET *
+C. * of set IUSET, in case that the spatial coordinates *
+C. * of the hits had been stored as the first three words *
+C. * in the argument vector of GSAHIT. *
+C. * If the character typed to pick is 'K' or 'k' then the *
+C. * kinematics of the corresponding track is also printed. *
+C. * The picking is repeated until the character typed is *
+C. * 'Q' or 'q'. *
+C. * EPSILO is the pick aperture, i.e. the first hit that *
+C. * falls into the square centered at U0,V0 (the pick point) *
+C. * with half length EPSILO is kept. *
+C. * If EPSILO is negative then its absolute value is taken *
+C. * and in addition the pick square is drawn. *
+C. * If EPSILO is zero there is no pick aperture and over all *
+C. * the hits the one nearest to the pick point is taken. *
