Note: When accessing files, be aware of the different formats these files and tables are in (File Structures).

• FOC:
• XREF (Reference files)
• XTAB (Reference tables)
• Types of data:
• Background, Intensity Transfer Functions
• Uniform DE, Spectrographic DE, Geometric, etc.

FOC reference data consists of 6 reference file types and 1 table type. The information listed below gives a simple discription of each along with how each are named. For further information on the naming conventions, go to File Structures.
