120 s – 50 Hz response
CMG-3B_120S_50HZ V
CMG-3TB or 3V / 3ESP borehole,
360 s – 50 Hz response
CMG-3B_360S_50HZ V
CMG-3TB or 3V / 3ESP borehole,
360 s – 100 Hz response
CMG-3B_360S_100HZ V
Some English descriptions are also accepted, e.g. “120s
velocity”, “100Hz acceleration” but this is not a free-format,
parsed field.
• To set the sensitivity (or gain) of the sensor components,
include the line
G=vertical-sensitivity,N/S-sensitivity,E/W-sensitivity
These values are given on the sensor calibration sheet. For
velocity sensors, they are given in units of V m
-1
s (V/ms
-1
). The
gain of an accelerometer is expressed in V m
-1
s
2
(V/ms
-2
).
Because Güralp Systems sensors and digitisers use differential
inputs and outputs, the sensitivity is quoted as
2 × (single-ended sensitivity) on the calibration sheet.
• To set the coil constants of the sensor components, include the
line
COILCONST=vertical-constant,N/S-constant,E/W-constant
These values are given on the sensor calibration sheet.
• To set the local acceleration due to gravity, include the line
GRAVITY=acceleration
You should give this value in ms
-2
, if you know it. If you miss
out this line, Scream! will use a standard average g value of
9.80665 ms
-2
.
