Tyler mentioned in a previous email that he thought it wasn't actually used, but I can re-enable it again if need be.</div>

In so far as Valery's plot is concerned, the dead-band value should be modified to not save so much data to Mya.</div>

<div class="x_PlainText">Hello Brian,<br>
maybe I'm wrong, Tyler can confirm it or not, but I remember that the <br>
averaging was enabled at some point to avoid fake alarms due to spikes <br>
in the readout of the values.<br>
We should make sure that disabling the averaging will not make the <br>
alarms system less stable.<br>
Thank you,<br>
