Correction:
in reality M1546 has been tested and NOT 1646. M1646 failed Reception due to not working ROC and graded C.
I hope we we will find a way to correct properly the module name and rerun MoreWeb analysis.

Dinko fixed logfiles and .tar file.

Results of M1646 has been removed with python Controller.py -d (remove all rows related to M1646).

M1637: C. Graded C due to not completed first test at -20C. Urs has reported issues. The second -20C after T-Cycle and test at +10C are graded A.
Tomorrow I'll upgrade this module manually to A
M1638: A
M1639: B Due to B at first -20C test. ROC8 mean noise >200electrons. Second -20C and at +10C both are graded A
M1640: B All three FT are B due to several ROCs mean noise >200electrons

Following procedure of regrading the first -20C test has been manually upgraded to B. The final grade is A since manual upgrade was not taken in to account. I do not know why. So, the module will be graded A.

M1629: B due to mean noise at -20C
M1630: C due to ROC1 with all pixels failed of PH calibration (Gain). Both FT at -20C are A!
Should be understood and retested. Put in C* tray.
M1631: B due to mean noise in all 3 FT
M1632: A

I have tested M1630.
I see not problem with ROC1. See the attached plot.
There is one dcol in ROC12 which shoes the "pattern" problem seen in a few other ROCs.
I think this module is fine, should be B. Could be retested.

M1630 is interesting because (I am using my terminology in the following) for the test at T=+10C ROC1 fails the PH optimization test and by consequence the gain/pedestal test is also failed.

The PH optimization test is failed because the minimum pixel on which the test is based is a 'dead' pixel (according to the PixelAlive test), but unfortunately has hits in the initial PH map. As a result the phscale and phoffset for this ROC are not optimal and this is seen in the gain/pedestal fits.

Please find the plots attached from the T=+10 tests.

Test results have been analysed with modified code:
M1615: B
M1619: A
M1620: B
M1622: B

One pixel of M1615 still failed mask test but it was not taken in to account in the final grading???
I put it in the shelves for Module doctor. To be decided what to do with this module.

For Wolfram one channel of M1615 does not work. He noticed that the cable has corrosion (probably this cable has been attached to a module that has been irradiated in Zagreb). After Reception test this module again graded C due to a mask test failure of one pixel in one ROC.

Wolfram proposed to grade this module as C*.

Entry  Fri Mar 20 18:32:34 2020, Andrey Starodumov, Full test, FT of M1609-M1612 
M1609 and M1611 are graded C
M1610 and M1612 are graded B

C and most B grades are due to many trimbit failures. Interesting that this time at +10C there are more failures then at -20C.

FT for these modules has been done on Mar 23
M1609: C
M1613: C
M1614: C
M1618: B

All C due to trim bit test failures

Entry  Thu Mar 19 18:01:50 2020, Andrey Starodumov, Full test, FT of M1605-M1608 
Only M1607 graded B. All others are graded C due to trimbit test.
M1606 should be looked carefully and may be retested since the threshold after trimming has strange features
(although not for all temperatures) that may mean that some trimbits really do not work.
Other modules to be re-analised without results of trimbit test or upgrade manually, since these results
are due to test algorithm. After trimming the threshold looks good for all failed ROCs.
Entry  Wed Mar 18 17:46:07 2020, Andrey Starodumov, Full test, FT of M1601-M1604 
M1601-M1604 passed full test
M1601: grade B
M1602-M1604: Grade C. The main reason is failed pixels during trimbit test.
To be understood the reason and to be upgraded manually.
