Alert level C
ABSTM02_ALERT_3_C  The ratio of expected to reported Tmax/Tmin(RR') is < 0.90
            Tmin and Tmax reported:      0.665     0.807
            Tmin' and Tmax expected:      0.760     0.807
            RR' =      0.875
            Please check that your absorption correction is appropriate.
