<div>Hi Bob, hi Marc,<br>
</div>
<div><br>
</div>
<div> I wanted to thank you again for the nice work.<br>
</div>
<div> The gas system works very well and its use could not be better. The interface to control is beautiful also.<br>
</div>
<div><br>
</div>
<div> One question, can I access it via clascss? Eventually it will need to be there I guess if the other gas control panels are controled via clascss. If not, then I'd be curious to know how the other detectors are doing.<br>
</div>
<div> In any case, while it is in the EEL building, is there a way to access it remotly? That would prevent unecessary use of gas when we are not trying to take data.<br>
