C  DT0STR1(k,i): t0 for wire k in layer i Straw 1 (STR1)
C
C  DT0STR2(k,i): t0 for wire k in layer i Straw 2 (STR2)
C
C  ITAREA1(j,i): Integral area thru the jth bin for ith layer of straw 1
C                normalized to 1.

C  ITAREA2(j,i): same as above for straw 2
C  Notice: in position 299 and 300 are kept the values of the time
C  window limits.
C---- Brief outline of the method
C--- S stands for integral where ^ (_) is the upper (lower) integration limit
C   Starting from S_0^X (dn/dx)dx = S_0^T (dn/dt)dt, being dn/dx the number 
C   of hits as a function of x ( distance from a wire) and dn/dt the number
C   of hits as a function of t, one has the following:
C   dn/dx=k is a constant (flat phi distribution), thus kX= S_0^T (dn/dt)dt.
C   Then dividing both terms by the total number of events N = kR, R straw
C   radius, one obtains X/R = S_0^T (dn/dt)dt /N. 
C   ITAREA1 and ITAREA2 are  S_0^T (dn/dt)dt /N as a function of T.
C   dn/dt is the measured time distribution
