PAW version 1.03/04

1- The command NTUPLE/CUTS has been modified in the following way:

 
 
  * /NTUPLE/CUTS  ICUT [ CHOPT FNAME ]
 
    ICUT       I 'Cut number' R=0:100
    CHOPT      C 'Options' D='P' R=' ,G,P,-,R,W,D'
    FNAME      C 'File name' D=' '
 
    Define cut number ICUT for an ntuple. This cut can then be used
    in subsequent commands NTUPLE/PLOT, PROJECT.
      CHOPT='G' define a new cut ICUT using graphics input on the latest
                1-DIM or 2-DIM projection of the Ntuple.
                In case of a 1-DIM projection, give 2 points cutmin,cutmax.
                In case of a 2-DIM projection, give up to 20 points to
                delimit the selected area. The polygon will automatically
                be closed by PAW.
      CHOPT='P' Print definition of cut number ICUT.
            '-' Reset cut ICUT
            'R' read definition of cut ICUT from file FNAME.
            'W' write definition of cut ICUT on file FNAME (text file).
            'D' Draw cut contour.
    Note that ICUT=0 means all cuts except for 'G' option.

2- The command NTUPLE/PLOT has been modified in the following way:

If NUPD is positive then every NUPD events, the current status of the histogram is displayed. The default identifier of the histogram being filled is IDF=1000000. At the next invocation of this command, the previous IDF=1000000 will be overwritten.

If NUPD is negative then the histogram being filled has IDF=-NUPD. IDF may have been created with H/CREATE. Before filling IDF, the contents of IDF are reset if IDF already exists. Use NTUPLE/PROJECT to cumulate several passes into IDF. Note that NUPD negative is a convenient way to force user binning. This option must be used when options '+', 'U', 'S' are specified in CHOPT.

3- A new command NTUPLE/UWFUNC is available.

  * NTUPLE/UWFUNC IDN  FNAME  [CHOPT]

    IDN 'Ntuple identifier' I
    FNAME 'File name' C
    +
    CHOPT 'Options' C D=' ' R=' ,E,P,T'
 
    Generates automatically the Fortran skeleton of a selection function.
      Example
         If Ntuple ID=30 has variable names [X,Y,Z,ETOT,EMISS,etc] then
      NTUPLE/UWFUNC 30 SELECT.FOR   will generate the file SELECT.FOR with:
          FUNCTION SELECT(XDUMMY)
          COMMON/PAWIDN/IDNEVT,X,Y,Z,ETOT,EMISS,etc
    *
          SELECT=1.
          END
    Then using the command EDIT one can modify this file which could then
    look something like: IDNEVT is the event number.
          FUNCTION SELECT(XDUMMY)
          COMMON/PAWIDN/IDNEVT,X,Y,Z,ETOT,EMISS,etc
    *
          IF(X**2+Y**2.GT.Z**2.OR.ETOT.GT.20.)THEN
             SELECT=1.
          ELSE
             SELECT=0.
          ENDIF
          END
    If CHOPT='E' then the local editor is invoked on FNAME.
            ='P' code to print events is generated.
            ='T' Tags for variables are generated in DATA.

4- Multi-Dimensional vectors are now implemented.

Using the file VECTOR.DAT described in the documentation try:

       VECTOR/CREATE  X(3,10000).
       VECTOR/READ  X  VECTOR.DAT.*
       VECTOR/PLOT  X(1)
       VECTOR/PLOT  X(1)%X(3)
