SIMC infiles/ with offsets 03/21/06

• The saturation corrected spcentral was used in the infiles
• The corrected values determined during the hee'p analysis were used for the hpcentral, h_thetacentral and s_thetacentral
  
• The hms oop and sos oop values were inserted into the infiles.  For example, in the PARAM/hmsflags.param file, the hms xptar offset was 1.1 mrad.  This was put into the infiles as   spec.p.offset.xptar = 1.1.  Similarly, the sos xptar offset was put into the infiles without changing the sign.
• The targ.zoffset was previously included in the infiles (0.23 cm) and is the position of the target (downstream is positive).
• The targ.xoffset and targ.yoffset were determined using the positions of the beam in the lab frame as determined by the 'calibrated' BPM's. 
  
• targ.xoffset = (BPM determined labx position of the beam)
• targ.yoffset = - (BPM determined laby position of the beam)
• a positive targ.xoffset makes the beam in SIMC move toward the HMS
• a positive targ.yoffset makes the beam in SIMC move above the target
  
• The spectrometer x offsets were kept at zero.
• The spectrometer y offsets were determined by looking at the mean ytar of the experimental data with the z=0 target, and calculating where the vertex should be using the BPM's.  The value used in the infiles was -(ytar_reconstructed - ytar_expected).
• The spectrometer yptar offsets were kept at zero.
