Detailed Description

Find discontinuities in every analysis channel Find variations in the bolometers' temperature trend by looking at the amplitude of the stabilization heater on each channel.

• Config example:

   module FindCDiscontinuities
   verbosity = info
   enable = true
   UseThermometer = true
   OutFileName = termometro.txt
   SmoothingTime = 8
   DebounceTime = 10
   NumberOfSigma = 2.
   DerivDistance = 20
   GraphicsOn = true
   MinimumPointsPerInterval = 20
   UseCorrectedAmplitudes = false
   endmod
     

Parameters:

• UseThermometer [bool = true]: if yes, the results of MFindTDiscontinuities module is also taken into account while breaking the measurement in time intervals
• OutFileName [string = "termometro.txt"]: ASCII file where the results of the modules are written. They will eventually go in the data base
• SmoothingTime [int = 8]: number of samples the amplitudes array are smoothed on
• DebounceTime [int = 10] number of samples the amplitudes derivatives are required to be above treshold for a discontinuity being identified
• NumberOfSigma [double 2.0]: the treshold on the first and second derivatives of A(t) is set to NumberOfSigma times the RMS
• DerivDistance [ int = 20]: two discontinuities found on derivatives of different order are discarded if closer than DerivDistance
• GraphicsOn [bool = true]: when true, some plots are produced for debugging
• UseCorrectedAmplitudes [bool = false]: set it to false if you need to stabilized non stabilized amplitudes set it to true if you need to stabilize already stabilized amplitudes
• MinimumPointsPerInterval [int = 20]: if two discontinuities are found closer than MinimumPointsPerInterval samples, one of them is discarded
