The script surf.pl


This perl-script must be called with the string number as option. It searches for "Surf","data" and "st[string number]" in the directory "$indir" (please edit in the beginning of the script). It will pipe all found data files (zipped or not) through the reader "reader" and book large ntuples with "bookcwn". The hbook-files will be stored in the directory "$outdir" (please edit in the script). Afterwards, PAW will be started and the script "bookhists.kumac" called. This short kumac loops through all events and stores the following histogram-files:

  • [filename].le: LE distributions of all affected OMs
  • [filename].adc: ADC distributions of all affected OMs
  • [filename].d[OM]: time difference distributions between all affected OMs and the reference OMs.

This is done with the help of three FORTRAN functions:

  • fillle.f: LE distributions of all affected OMs
  • filladc.f: ADC distributions of all affected OMs
  • fillref.f: time difference distributions between all affected OMs and the reference OMs.

All histograms are first filled in the working directory (/net/amanda/surft0/) and then moved to the directory "$histdir" (please edit in the script), with subdirectories for each string number. Because of HBOOK restrictions in the length of a file name (only 32 characters), all useless characters will be stripped off the file name.

Booked histogram-files can be easily accessed in PAW with the command: 
hi/file [lun] [filename]
One histogram-file contains 680 histograms.

The reference OMs are stored in the array "@refoms". A change of this array is sufficient to have reference OMs modified throughout the whole booking process.

At the end, "surf.pl" will give you some run statistics, e.g.:

Skipped files occur whenever the hbook-files exists already with non-zero file size.
You should delete the hbook-files, now.

HAVE A LOT OF FUN!!!
