===Fix the calibration data stored in the RSQ header===

You can see what calibration file is stored with your scan a few ways. One is to use <code>aix -l</code> to view the log file. You should see this part:

 !-------------------------------------------------------------------------------
 Mu_Scaling                                       8192
 Calibration Data              60kVp, BH: 200 mg HA/ccm, Scaling 8192            
 Calib. default unit type      2 (Density)                                       
 Density: unit                 mg HA/ccm                                         
 Density: slope                         1.40254895e+03
 Density: intercept                    -3.40953003e+02
 HU: mu water                                  0.23900
 !-------------------------------------------------------------------------------

Another is to use the extended header command for RSQ and ISQ files:

 $ run ut:UCT_EXT_HEADER_DISPLAY.EXE

If you need to fix it, use the <code>UCT_EXT_HEADER_ADD_CALIB.EXE</code> command:
 run ut:UCT_EXT_HEADER_ADD_CALIB.EXE
 
 UCT_EXT_HEADER_ADD_CALIB V 1.1
