2. 20 th CAA Cross-Calibration Workshop MPS, Göttingen, Germany 15-17 Oct 2014 2 Introduction  There are several similar datasets where the main difference is that data vectors or matrices are converted into another system. For instance, scientific data are given in different scientific units or coordinate systems  Consistence of such datasets have never been investigated although there is some evidence that some errors can occur  Such similar datasets can often be expected to have the same number of records  Exception: if a dataset is given in raw units, the corresponding datasets in scientific units may have less records if poor records were deleted  However, if poor data have been replaced with FILLVAL, the same number of records should exist  In addition such datasets should have similar values for  Version numbers  Generation and ingestion dates  Note: these metadata can have significant differences, so there is no automatic  CAA has developed a tool that collects such metadata and gives them in an xml file
