Dear Sunil,
00 and 10 represent the locations where the bore hole (STS 2 ) seismometer and the shallow Guralp CMT 3G seismometer are installed respectively at PALK station.

Hi Sunil,
00 and 10 etc represents the Location code, in this case
represents different instruments en the same place (Station PALK),
i see in the IRIS II network and the 00 (BH?)correspond to the Borehole
instrument Geotech KS-54000, and Location 10 (BH?) correspond to GMG-3T
Guralp instrument, see here: http://www.iris.edu/dms/mda.htm and
search for II Network and then for PALK station.
HTH,
Milton

Dear Sunil Roy
00 and 10 is location code
Some stations, in particular IRIS stations, use location codes. In this
case you have to enter the location code here. Typically ?00? for STS-1 or
?10? for STS-2 seismometer.
If they has the same SPS they aren't diferents.

Hello Abderrahim,?
Qc generally refers to scattering attenuation and if you want to calculate that, you may look at the following paper:
Leyton, F., and K. D. Koper (2007), Using PKiKP coda to determine inner core structure: 2. Determination of QC,
J. Geophys. Res., 112, B05317, doi:10.1029/2006JB004370
On the other hand, if you are referring to Q in general, then you may have to use a synthetic seismogram algorithm like reflectivity.?
Januka.

Dear Sac Users,----------------------------------------------------------------
I have download data form IRIS, which is in seed format.
Late I have converted it to sac format. I found that for some
event two sac files are present with different file name as:
2011.365.00.39.00.0195.II.PALK.00.BHZ.M.SAC
2011.365.00.39.00.0195.II.PALK.10.BHZ.M.SAC
After closely looking at the header I found that they have
different value in khole. So in the file name 00 and 10 represents
khole value. If it is khole then what it represents. Which file should
I take for my analysis. If not then why this two files are different.
with regards
Sunil
