Attached please find HSP phase data for the second part of 2004 and first
part of 2005.
The data has not been quality checked and they come in "wxsa" format. Some
data from this
station comes in "wxs" format that differs from "wxsa" in that it has lines
of blanks, lines of
minuses and comments of the sort "Work saved to
E:\!wysy|ka\HSP050911741.wxs"
in between individual events.
Format example:
Phase Pg e . HSP 1 EHZ 2004 9 15 13 31 5 634
Phase (Sg) e . HSP 3 EHE 2004 9 15 13 31 10 117
Phase P e - HSP 1 EHZ 2004 9 15 19 22 44 414
Phase P e . HSP 1 EHZ 2004 9 17 7 44 16 261
Description:
Each phase is one line, elements in the line have variable number of
characters and are
separated by spaces.
1. Phase: phase identificator. Should there be anything here other than the
word "Phase", the
line does not contain phase information. However, such "non-phase" lines
should have been
filtered out from what you got.
2. Phase name
3. e/i, emergent/impulsive qualifier
4. +/- compression/dilatation qualifier. Or dot if no qualifier given.
5. Station code
6. Channel number. Valid channels are 1=Z, 2=N, 3=E, but in principle higher
numbers may
happen as the HSP station has auxillary channels from one other 3-component
site and 4 single
component sites at distances about 2 km from the main site. These auxillary
sites are located
on Hans Glacier and are kept for the studying of icequakes. They should not
show up in
the desciption of earthquake signals, however you cannot be 100% sure.
7. Component. Choices are EHZ,EHN,EHE,SHZ,SHN,SHE. The last character
denotes
component. The first character "E" denotes the 100 sample-per-second trace,
"S" denotes
20 sample-per-second trace. Sometimes the component is not given, sometimes
it reads
"
