CheckCIF-RADNT01

PROC-NAME: RADNT01 Type_1

PURPOSE: Check that the radiation type is recognised.

PROCEDURE:

(1). Check that the _diffrn_radiation_type contains one of the

following.

CHECKLIST:      

        'Cu K\a'

        'Mo K\a'

        'Ag K\a'

        neutron

        synchrotron

Otherwise issue ALERT A

        "Alert A The radiation type doesn't match a standard keyword"

        _diffrn_radiation_type must ONLY be one of the following keywords (do not add extra text to this field and watch the formatting e.g. 'Cu K~\a~' and 'Cu Kalpha' are incorrect, the space before K should be present):

        'Cu K\a'

        'Mo K\a'

        'Ag K\a'

        neutron

        synchrotron

        If you used a less common X-ray source, such as a gold X-ray tube, this alert can be ignored. The keyword 'synchrotron' should be used for all work carried out on a beam line.
