| Classes of Blue Files: Type 1000 One-dimensional data. Typically used for raw signal data. Type 2000 Two-dimensional frame based data. Typically used to show Frequency vs Time (e.g. post-FFT signal data). Type 3000 Record-based data (limited to 26 subrecords). Similar to a flat-file database. Rarely plotted, but frequently listed. Type 4000 (Not supported by NeXtMidas) Key/value pairs, used by X-Midas as a work-around for not having tables. Type 5000 Record-based data (limited to 14 subrecords) with system modeling parameters. Typically used for geodetic positions and features. Type 6000 An extension of Type 3000 files, allows for more complex records. Most newer applications prefer to use XML over Type 6000 files. Types of Blue Files: Each of the above classes has one generic form (e.g. Type 1000 for the class of Type 1000 files) and many specific forms (e.g. Type 1001, 1002, and 1003 for the class of Type 1000 files). The specific types in a class tell the processors that there is a special way in which the file should be interpreted. Example: A Type 1999 file stores sets of connected points that need to be plotted in a special way (see world.prm). (While it is less confusing to refer to the type classes as Type 1xxx, 2xxx, 3xxx, etc (rather than Type 1000, 2000, 3000, etc), this is not the accepted practice of the Midas community.)
