[Antelope] overriding sensor sensitivity in dbbuild files

[Markova, Nina]

Hello,

I have a question about overriding sensor sensitivity in dbbuild files.
It is easier for me to explain it with an example.

For station GAC we use file cmg3esp_60sec.

time 2011-11-25 13:49:00
sta     GAC   45.7033  -75.4783    0.0620 GLEN ALMOND, QC
datalogger taurus_inf_G00 dCN0046
sensor cmg3esp_60sec  0.00 T34611
   samplerate  100sps
add

In file data/responses/cmg3esp_60sec the default gain value is 2000/v/m/sec (the file is copied below).
For GAC.HHZ it is 1500.

How can we override this value (to be 1500) in dbbuild files? What keyword/command do we add?

sta     GAC   45.7033  -75.4783    0.0620 GLEN ALMOND, QC
datalogger taurus_inf_G00 dCN0046
sensor cmg3esp_60sec  0.00 T34611
   samplerate  100sps
   command/keyword?     1500
add


>From the dbbuild_batch man page:
axis label hang vang [sens [lead [pgain [pstage]]]]
Should I use axis?
It will be helpful to give us an example.
