I think this should be decided by Frazer and Paul. It is very good to know what the issues are but we have to be careful that we don't pull Paul in too many directions at once. <br><br><div class="gmail_quote">On Thu, Mar 7, 2013 at 4:56 PM, Rick Perley <span dir="ltr"><<a href="mailto:rperley@aoc.nrao.edu" target="_blank">rperley@aoc.nrao.edu</a>></span> wrote:<br>

Hi All, <br>
A note of caution here:<br>
<br>
We have agreed in the low-band telecons that Frazer runs that the current low-band priority to focus on receiver build and installation is reasonable. This means that we should not put effort into fixing anything wrong with P-band receivers right now. Just collect the problems and deal with them after we have finished the installation. <br>
So right now, although it is useful to know what receivers have problems and what those problems may be, we are not going to spend effort fixing those problems right now because it takes away too much effort from actually building receivers. <br>
The only scenario in which this would change is if Frazer decided that it is best to change those priorities. That said, what Rick is doing is valuable and will be needed in the near future. <br>
Cheers,<br>
Deb<br>

These two have their ploarizations swapped. Is it feasible for<br>
Paul to consult with Jerry L about how to remedy this?<br>

I claim that these are turned on by the executor at every scan unless<br>
the script explcitly requires them to be off. model2script does not<br>
generate scripts which does that, so they should all be on. If not,<br>
it must be an F320 or F14 problem. There is more than one way to<br>
command the F320 to turn on the cals; perhaps one is more equal than<br>
the others.<br>
