FRIDA implementation note: documentation of historic data formats
Note that these formats are largely isomorphous, since the data model has little changed over the years. The last major change was the introduction of multi-z-coordinates (probably along with the i96-Format).
Used in preliminary versions of Frida-2. File name extension “.a01”. A sample file with 2 spectra:
