Hi,
I am looking for data for YH 2004-2007 (Parkfield reoccupation). There are BH channels for all stations for a couple of days (e.g. 2004_11_17), after that only one station returns BH intermittently (CRAK only from 2004_11_19 to 2005_10_11, POLE only from 2006_01_01 to 2006_10_26). There seem to be SH and EH channels available for other stations, but the HH and BH channels appear to be missing (e.g.
https://ds.iris.edu/wilber3/find_stations/2182767, subsetted for YH), even though BH channels are listed as archived in the metadata (e.g.
http://ds.iris.edu/mda/YH/TANK/?starttime=2004-10-15&endtime=2007-12-31). Is there a way to access BH channels for all stations for this network for the entire deployment time?
thanks!
Vera
