For both, the warmest good reading was 144.38. Below that all readings have been crazy:</p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java"> 2018-04-30 07:35:12.180Z cmds 20 Actor.py:491 <span class="code-keyword">new</span> cmd: temps status 2018-04-30 07:35:12.181Z root 10 feeControl.py:798 sending command :<span class="code-quote">'~rt,FEE\n'</span>: 2018-04-30 07:35:12.184Z root 10 feeControl.py:856 received :~rt,FEE: 2018-04-30 07:35:12.242Z root 10 feeControl.py:856 received :291.50: 2018-04-30 07:35:12.242Z root 10 feeControl.py:798 sending command :<span class="code-quote">'~rt,PA\n'</span>: 2018-04-30 07:35:12.246Z root 10 feeControl.py:856 received :~rt,PA: 2018-04-30 07:35:12.447Z root 10 feeControl.py:856 received :270.63: 2018-04-30 07:35:12.447Z root 10 feeControl.py:798 sending command :<span class="code-quote">'~rt,ccd0\n'</span>: 2018-04-30 07:35:12.451Z root 10 feeControl.py:856 received :~rt,ccd0: 2018-04-30 07:35:13.119Z root 10 feeControl.py:856 received :19199440.48: 2018-04-30 07:35:13.119Z root 10 feeControl.py:798 sending command :<span class="code-quote">'~rt,ccd1\n'</span>: 2018-04-30 07:35:13.123Z root 10 feeControl.py:856 received :~rt,ccd1: 2018-04-30 07:35:13.790Z root 10 feeControl.py:856 received :18203293.12: 2018-04-30 07:35:13.791Z cmds 20 CommandLink.py:121 &gt; 1 21590 i ccdTemps=270.63,19199440.48,18203293.12 2018-04-30 07:35:13.791Z cmds 20 CommandLink.py:121 &gt; 1 21590 : </pre> </div></div> <p>I feel that we have seen this before and that it was fixed (it must have been).

CCD temperature readings are nuts,

Task Normal Won't Fix Won't Fix shope cloomis Mon, 30 Apr 2018 07:51:59 +0000 Thu, 12 Jul 2018 19:44:18 +0000 Thu, 12 Jul 2018 19:44:18 +0000 ics_xcu_fee 0 3 <p>We saw this before and did not fix it because 145K is 30K below operational temperatures, and there are other sensors near the CCD without this problem.</p> <p>Measurements were below the physical measurement limits imposed by the hardware. All measurements are returned in Kelvin which means they cannot be negative. Firmware was modified to return -1.0 for measurements below the normal operating range.</p> <p>See comments: This will not be an issue during operation, we do have other &#8211; not clipped &#8211; temperature sensors on the FPA, and the firmware now reports a sensibly invalid reading.</p> Development Rank 0|ii04e7:
