3V-CPI / 2DS

Translator to convert the 2DS portion of the 3V-CPI, as well as standalone 2DS, data from SPEC compressed format into the generic OAP file format.  Converting to the generic format makes the data usable by xpms2d and process2d.  translate2ds will uncompress the data, so raw 4k buffers will expand into multiple buffers.  The same data-system time stamp is replicated to all output buffers, beware when subtracting time slices.

Specifications for output format are here http://www.eol.ucar.edu/raf/Software/OAPfiles.html
