A complete archive of the Yohkoh data for the whole mission is available on Magneto-Optical (MO) disks at ISAS.
A Unix script and associated alias is available to mount and dismount MO (magneto optical) disks at ISAS. An IDL interface routine is also provided to allow MO mounts and dismounts from within an IDL session or callable from other IDL routines. Once mounted, access to data on these drives is identical to other magnetic disks - standard Unix operations (ex: ls) are permitted. For MO disks containing Yohkoh data, the standard IDL functions (ex: yodat access) are available.
MO disks are available on several machines of the SUN machines at ISAS. including flare3, flare4, flare6, flare13, flare14, flare15. The first (and in most case, only) MO drive on any machine is referred to as drive 0. Some machines may have a second drive (drive 1) - all drives are clearly marked with a drive number. Find an available (empty) drive and insert your disk - if you intend to write, verify that the write protect switch allows writing. By default, the mount is executed on the machine which contains the MO driver. If that machine is different than the machine which executes the command, then the MO disk is automatically 'exported' and mounted on the local machine. Use the /all switch to force mounting on all ISAS machines.
