some chinese translation tools

OT = off topic

(1) old standby babel fish - type in english or paste chinese characters, get unintelligible response

http://babelfish.yahoo.com/translate_txt

(2) draw the character with your mouse and get the closest matches. okay for characters without a hundred strokes. can't cut and paste the result easily, but you get the pin yin and tone.

(3) chinese word processor and dictionary. extremely useful if you know pin yin. might only be 30 days free.

error in transfer

If you get this error when applying transfer in sac:  

check_channel; decimation blockette with no associated filter,

skipping to next response now

No transfer function applied! 

ERROR 2118: No transfer function applied.

Then go into the RESP file and make sure that the blocks for each stages are in the following order (cut and paste if necessary):

FIR response

Decimation

Channel Gain

Xming for xwindows.

Run Xlaunch for multiple windows.

Then in SSH under tunneling settings, check Enable X11.

station lat/lon to 3 decimal places

On the IRIS site the seismic station locations are only given to 2 decimal places lat/lon, which is +/- l km. They don't want to real the precise position of the instruments.

If you need more info, location to 3 decimal places is available in the .sac files.

(from rob)

In the sac header files you can find the latitude and longitude to at least 3 decimal places. You can access this either via sac:
read (file)
lh stla stlo

or a couple matlab options based on which sac reader you're using
with load_sac:
[header, data] = load_sac('file');
header.stla, header.stlo

(In the above two cases stla is short for station latitude and stlo is short for station longitude)

or with readsac
[time, amp, header] = readsac('file');
header(17)
header(18)

in this case header(17) is the latitude and header(18) is longitude.
