Problem with reliability flag values for v3 MST Radar radial data files produced prior to 10th May 2007
Owing to a bug in the file-writing software, v3 MST Radar radial data files produced prior to 10th May 2007 do not not contain correct reliability flag information, i.e. the variables:

• signal_component_is_reliable
• signal_component_reliability_details

only contain values of 0. The software was fixed on 10th May 2007 and so files for data dates including and after 10th May 2007 are free from this problem. Files for data dates prior to 10th May 2007 will gradually be re-created. If you are uncertain as to whether or not you have a corrected file, check the creation date which is recorded in the netcdf global attribute history.

This problem does not affect v3 MST Radar Cartesian data files
Since the reliability flags in the Cartesian files are used to determine which data should be included in the quick-look plots, it is known that they are not affected by the same problem.
