2.4. Scanning

Once MUSE is compiled, one can scan the parameter space:

1. set

   scan mode (store to BANK)

   in `nume.dat'.
2. run the following simple perl script (adapt the parameters to your scan)
   ATTENTION: such a scan can take a very long time:
   please check first with ten points or so to calibrate the granularity of your scan.

   #!/usr/bin/perl
   # This script is scanning two variables within given interval
   # and with a given step, put them in the DATA file
   
   $xmin = 50;
   $xmax = 60;
   $xnstep = 101;
   $xstep = ($xmax-$xmin)/($xnstep-1);
   
   $ymin = 165;
   $ymax = 200;
   $ynstep = 71;
   $ystep = ($ymax-$ymin)/($ynstep-1);
   
   $tanbe=2;
   $a0=0;
   $sgnmu=+1;
   
   foreach $nx (0..$xnstep-1){
   $x = $xmin + $nx * $xstep;
   foreach $ny (0..$ynstep-1){
   $y = $ymin + $ny * $ystep;
   $m12=$x;
   $m0=$y;
   open (MUSE,"|cat > DATA/scan.dat; time muse> /dev/null") || die"

   Error: \n";
   print MUSE "$tanbe 'tan(beta)'\n";
   print MUSE "$sgnmu 'mu'\n";
   print MUSE "$m12 'm1/2'\n";
   print MUSE "$m0 'm0'\n";
   print MUSE "$a0 'A0'\n";
   close MUSE;
   }
   }
   

3. all the result are stored in a BANK.hex file, ready to be transfered in an n-tuple.
