Actions

• Feature request: do checkpointing when instruments are down
• Feature request: need to hook up equivalent of "CAT 2" vetoes to online analysis when ready, and HW inj veto, etc.
• Document the parameters in mkLLOIDmulti()
• Check if bank ids are the same across different instruments
• Feature request: Make time-frequency videos for interesting events
• Inject signals of known, high SNR and measure loss
• move the makesegmentsrcgate to before the matrix mixer, not in the current sum-of-squares control loop
• Make conditional branches in the graph gray boxes
• consider zero padding the beginning of jobs to get rid of mkdrop()
• Decide how to properly normalize SNRs for incomplete filter segments (currently filters are not renormalized so the loss in SNR is bigger than might be expected)
• Check and possibly fix the function that switches between time-domain and FFT convolution based on stride and number of samples
• Consider if quality = 9 is right for downsampling (it should be plenty good, but maybe excessive?)

Functions/classes not reviewed since they will be moved

• DetectorData
• mkSPIIRmulti
• mkSPIIRhoftToSnrSlices
• mkLLOIDSnrSlicesToTimeSliceChisq
