Alert level C
ABSTM02_ALERT_3_C  The ratio of expected to reported Tmax/Tmin(RR') is < 0.90
            Tmin and Tmax reported:      0.837     0.988
            Tmin' and Tmax expected:      0.937     0.988
            RR' =      0.893
            Please check that your absorption correction is appropriate.
PLAT061_ALERT_3_C Tmax/Tmin Range Test RR' too Large .............       0.89       
PLAT063_ALERT_3_C Crystal Probably too Large for Beam Size .......       0.64 mm    

   0 ALERT level A = In general: serious problem
