Fast Simome MBAR program; no correction on exponential underflow.

mbar filePARM fileDATA [ > weight_FILE]

filePARM is the parameter file (the REM.set file) 
This input file for mbar can be generated from the ORAC REM.set with the command

awk '{if($1 ~ "[0-9]" ) print $2, $3,$4}' PAR0000/REM.set > mbar.parm 

fileDATA is the (energy) data file in RT units (T is the
the temperature of the H-REM GE.) and contains all unscaled 
energies sampled in the GE.   
This mbar input file can be generated for the energy file 
produced by orac with the command: 
  
awk '{print $2, $3/2.4942, $4/2.4942, $5/2.4942}' energy_file > mbar.dat


weights for each GE point whose (unscaled) energies are specified in fileDATA 
are printed to StOUT.
