Working Group on Data Conversion
Meeting Notes November 5, 2008

Attending: Withers, C. Chiu, J.-M. Chiu, H. DeShon, Smalley, Asmerom

The action items from the previous meeting were reviewed.

Mitch did create some space on deagol for Bini to work.

Mitch didn't have time to contact Ahern to verify the legality of using antelope with permanent network data (e.g. Mt Carmel datasets) nor to find out what datasets IRIS will archive (JerMing has a network code to use for the Panda submissions).

Heather did review antelope basics with Christy and Bini.

Mitch came up with this rudimentary list of the 160GB in the fdl data space:

Clearly we need to clean this up.

Jer-Ming gave this list of Panda datasets and approximate space:

• San Juan 40GB
• New Madrid 6GB
• Hawaii 4GB
• New Zealand 20GB sp triggered and not sure how much bb continuous.
• New Zealand Panda II 4GB
• Taiwan Panda II 8GB

Heather has space we can use temporarily for the panda data. Need to make it accessible from the suns. All the panda data are on a 70GB scsi disk but the disk was damaged by lightning. JerMing thinks the actual disk is ok and just the scsi interface is damaged. Mitch will get someone (Brewer?) to try to read the disk with a different interface. If the disk is unreadable, then the original 8mm Exabyte tapes need to be re-read ASAP as they are beyond their 10 year life expectancy.

Bini is finished with the San Juan database except for responses. JerMing reports that the analytical equation is available but the pole/zero solution is on the failed 70GB disk. Herrmann (and maybe Chuck?) also have the poles/zero responses. JerMing will ask Herrmann for it.

Once we get the responses into the San Juan database, Heather volunteered to turn the db2seed crank. She also volunteered vet Bini's notes and noted that we'll then have a README for the panda format and the seismic network format (Mt Carmel is complete) for Christy to use for the other datasets.

A seperate database was made for Mt Carmel that includes only triggered event data. This was parsed from the continuous database to facilitate sending a tarball to Indiana.

Bob noted that books are in the archive room that describe every trigger and a pql snapshot of every trigger was printed. This are linked via either time or filename. We should be careful to preserve this linkage in case anyone in the future wishes to combine the two information sources.

Mitch will draft a report for the directory before the end of November.

The committee will meet again in late January. Date and time TBD.
