omc_dcpd_output_to_darmin1_tf seems to be the inverse of what it is named

omc_dcpd_output_to_darmin1_tf has a value of 1592920.0 From the name I would assume that this is a transfer function from dcpd_output (which is mA as reported by DCPD sum channel, or "fake mA") to DARM err, so that it would have units of DARM err counts / fake mA

Using DTT to look at this a time when we were locked, the transfer function from DARM err to DCPD sum is 1.59577e6, (ie, that number has units of fake mA/ DARM err counts.

So I think the name is inverted, and this quantity should be called darmin1_tf_to_omc_dcpd_output (or keep the name the same and divide by 1).
