9.5.7} USRCOLL output

 ---------------------

 Option USRCOLL produces either formatted or unformatted output (for the
 latter, see USRTRACK description for instructions on how to read it - the
 two options produce output with identical format).

 As for most other estimators, a complete description in
 clear of the requested scoring is printed also on the standard
 output. For instance:

    Coll  n.   1  "collogchf " , generalised particle n.  202, region n.     6
       detector volume:  4.0000E+01 cm**3
       Warning! Collision estimators not implemented for electrons/positrons and photons
       logar. energy binning from  1.0000E-11 to  1.0000E+00 GeV,  1000 bins (ratio : 1.0257E+00)
       data will be printed on unit   24 (unformatted if < 0)

 After the title and date, and one line reporting the total number of particles and their weight,
 the header of the formatted output is very similar to the above text:

  *****  Test collision estimator                                                          *****

            DATE:  1/ 5/ 5,  TIME: 18:32:28

           Total number of particles followed  100000, for a total weight of  1.0000E+05

    Coll  n.   1  "collogchf  " , generalised particle n.  202, region n.     6
       detector volume:  4.0000E+01 cm**3
       logar. energy binning from  1.0000E-11 to  1.0000E+00 GeV,  1000 bins (ratio : 1.0257E+00)
       Data follow in a vector A(ie), format (1(5x,1p,10(1x,e11.4)))

 As for most other estimators, the matrix is easily read and manipulated by a simple
 program, using the format reported in the header. It can also be cut and pasted into
 a spreadsheet.
