Program PseSacGenMH.f generates a SAC file of minimum header from PSE data in Exabyte tape format. The generated SAC file is for a temporary use only. It cannot be archived because none of the vital information for archiving, such as time, station, component, etc. are not in the header. The program calls decoding routines in three files: Ntimex.f, lpedit.f and spedit.f. The maximum data length is limited to 60 Exabyte data blocks for LP data in old format, or 30 blocks for LP data in new format, both corresponding to about 2 hours 43 minutes; or 7 blocks for SPZ data, or about 19 minutes. This is a simple, basic program. Please feel free to expand it to fit your need.

For other computers, you may need to revise the program accordingly.
