I believe these are the Denali GPS seismology results as published in BSSA
We converted the results into SAC and attempted to archive these files at IRIS. We belatedly discovered that IRIS had improperly an instrument response to our records, thus contaminating them.
There is an ascii dump as well as the original SAC files.
All Questions regarding the analysis or file formats should be sent to Andria Bilich at NOAA.
I have also included some Tokachi-Oki files here that I found on my laptop.
