### Calibration matching

            LAS\SET CALIBRATION [Beam_Tol [Gain_Tol]] or OFF

        Specify the tolerance on the Beam efficiency (Beam_Tol) and  gain  image
        ratio (Gain_Tol), on turn or calibration checking. A value of 0 means no
        check. The default values are 0.02 and 0 respectively.

        These values are used by commands ACCUMULATE and AVERAGE to verify  that
        the calibration is consistant. They are also used by command WRITE which
        writes the corresponding information in the output file only if Beam_Tol
        is  non  zero. Note that because the beam efficiency is less than 1, you
        could use Beam_Tol=1 to suppress  the  calibration  checking  but  still
        write the information.
