Alert level C Value of measurement temperature given = 90.000 Value of melting point given = 0.000 PLAT024_ALERT_4_C Merging of Friedel Pairs is Indicated .......... ! PLAT066_ALERT_1_C Predicted and Reported Transmissions Identical . ?
Alert level G REFLT03_ALERT_4_G ALERT: MoKa measured Friedel data cannot be used to determine absolute structure in a light-atom study EXCEPT under VERY special conditions. It is preferred that Friedel data is merged in such cases.
