The script will ask you to fill in sensor calibration parameters for each
component you have selected.
10.
Most data can be found on the calibration sheet for your sensor. Under
Instrument response
, you should fill in the sensor response code for your
sensor, according to the table below.
Instrument Type
should be set to the
model number of the sensor.
11.
If the file
calvals.txt
exists in the same directory as Scream!'s executable
(
scream.exe
), Scream! will look there for suitable calibration values. A sample
calvals.txt
is supplied with Scream!, which you can edit to your
requirements. Each stream has its own section in the file, headed by the line
[
instrument-id
]
. The
instrument-id
is the string which identifies the
digitizer in the left-hand pane,
e.g.
GURALP-DEMO
. It is always 6 characters
(the system identifier) followed by a dash, then 4 characters (the serial
number.) For example:
24
