===Modify RSQ's BHC for in-air scans===
This is necessary because the beam-hardening correction factor assumes scans were done in soft tissue.  It is necessary to choose calibrations of 1200 or 700, instead of the default 200.

Currently, the XtremeCT has options for 200 (standard) or 1200 calibration (in air). 

To do this, log in as users <code>calibration</code> and then:

<pre>
$ set proc/priv=bypass                         ! as user calibration; modification of MICROCT user data
$ run ut:UCT_EXT_HEADER_ADD_CALIB.EXE
> Raw-Data-File []: DISK2:[MICROCT.DATA.00000401.00001495]C0001404.RSQ
> ...
> Add another BH-Corr from file again? (Y/N) [N]:    ! Enter yes (UCTD:UCT_BH_COEFF_60KV_1200HA_3309.TXT)
</pre>

Then, <b>delete</b> the old ISQ.  It must be deleted or else the header information will not be changed.  Finally, reconstruct the new ISQ and analyze...
