TRANSP data is identified by the tokamak (e.g., TFTR), the shot year, and a TRANSP run identifier, either a four digit run number or an eight character ``shot-try'' string. Run results are archived on the optical disk system. Runs prior to September, 1989, that have never been restored to disk (i.e., runs done before the optical disk implemention) can be restored from tape with GETRUN. GETRUN can also provide a list of TRANSP runs.
Read $ HELP TRANSP if you want to use GETRUN or the RPLOT utility that displays TRANSP results. Doug McCune maintains the TRANSP data.
