UCoMP GBU seems to be failing for TU_LCVR when it shouldn't #27

Closed bberkeyU closed 1 year ago

bberkeyU commented 2 years ago

A spot check was done for one of the FITS files to show the problem, but it appears this issue applies to all/most of the data files taken recently.

From the 20211107.ucomp.1074.gbu.log we see the following:

Filename                                 Reason
20211107.192028.ucomp.1074.l1.5.fts           3
......
GBU bitmask codes
Code    Description
    1   at least two identical TU_LCVR{1,2,3,4,5} temperatures
    2   a temperature is outside the nominal range
    4   sequential extensions were acquired more than 10.00 secs apart

From the 20211107.192028 header we get the following temps:

TU_RACK =               19.242 / [C] Computer Rack Temp Unfiltered              
TU_LCVR1=               34.543 / [C] Lyot LCVR1 Temp Unfiltered                 
TU_LCVR2=               34.493 / [C] Lyot LCVR2 Temp Unfiltered                 
TU_LCVR3=               34.576 / [C] Lyot LCVR2 Temp Unfiltered                 
TU_LNB1 =               34.569 / [C] LiNb1 Temp Unfiltered                      
TU_MOD  =               27.901 / [C] Modulator Temp Unfiltered                  
TU_LNB2 =               34.477 / [C] LiNb2 Temp Unfiltered                      
TU_LCVR4=               34.449 / [C] Lyot LCVR4 Temp Unfiltered                 
TU_LCVR5=               34.203 / [C] Lyot LCVR5 Temp Unfiltered                 
TU_BASE =               30.789 / [C] Instrument Baseplate Temp Unfiltereed      
T_C0ARR =                      / [C] Camera 0 Sensor array temp                 
T_C0PCB =               27.000 / [C] Camera 0 PCB board temp                    
T_C1ARR =                      / [C] Camera 1 Sensor array temp                 
T_C1PCB =               26.500 / [C] Camera 1 PCB board temp

Per src/gbu/ucomp_gbu_check_identical_temps.pro we should only see this reason when 2 of the TU_LCVR values are identical or different by less than .0001. But all of the TU_LCVR values are different and the smallest difference is .033V.

For some reason the camera ARR temps failed to get written to the file; so this should fail for Reason 2 not 3 (2+1).
