[data-issues] Electromagnetic_Data_Access_Problem

[Saranti Anna]

Hallo,

we are trying to download data from the BK network
through iris, with the slinktool program.
The BK belongs to iris according to: http://www.iris.edu/stations/networks.txt

We are interrested in the electromagnetic data from station PKD. Although we can download seismic data, for example BHZ.D :

./slinktool -s 'BHZ.D' -S 'BK_PKD' -tw 2007,10,13,19,00,00:2007,10,13,20,00,00 -o output.mseed -nt 10 -p -vv bud.iris.washington.edu:18000
 
there are no data coming with VT1.D:
./slinktool -s 'VT1.D' -S 'BK_PKD' -tw 2007,10,13,19,00,00:2007,10,13,20,00,00 -o output.mseed -nt 10 -p -vv bud.iris.washington.edu:18000

Although we find this kind of channel in: 
 http://www.ncedc.org/ftp/pub/doc/BK.info/BK.stations, and
 http://www.ncedc.org/dart/BK/PKD.BK/

We get:
slinktool version: 3.8
Parsed 1 streams from stream list
[bud.iris.washington.edu:18000] network socket opened
[bud.iris.washington.edu:18000] sending: HELLO
[bud.iris.washington.edu:18000] connected to: SeedLink v3.0 (2006.104dmc)
[bud.iris.washington.edu:18000] organization: BUD Near Real Time - IRIS DMC
[BK_PKD] sending: STATION PKD BK
[BK_PKD] station is OK (selected)
[BK_PKD] sending: SELECT VT1.D
[BK_PKD] selector VT1.D is OK
[BK_PKD] 1 selector(s) accepted
[BK_PKD] requesting specified time window
[BK_PKD] DATA/FETCH/TIME command is OK
[bud.iris.washington.edu:18000] 1 station(s) accepted
[bud.iris.washington.edu:18000] sending: END

-> Can anyone help? Is it because electromagnetic data differ from
     from seismic data?

     Thank you very much,
     Saranti Anna
