Alert level B
ABSTM02_ALERT_3_B  The ratio of expected to reported Tmax/Tmin(RR') is < 0.75
            Tmin and Tmax reported:      0.588     0.992
            Tmin' and Tmax expected:      0.971     0.992
            RR' =      0.606
            Please check that your absorption correction is appropriate.
