TDMoptfilter : Optimal filter fit of TES pulses in the time domain using alternate filters

tesfdmtools.methods.TDMoptfilter.optfilter(hdf, channel, freq, indx, base1, base2, noisspec, debug=False, prlen=None, rotate=False, risetime=False, bsec=0.05, absolute=False, nppos=11, shiftpulse=False, flip=False, wrtfilter=False, usefilter=None, **kwargs)

perform optimal filtering fit of individual pulses (for time domain), using alternate filters

Args:

• hdf = HDF5 input file object

• channel = channel number being processed

• freq = frequency number (pixel) being processed

• indx = index of selected events, to be processed

• base1 = baseline level at start of record

• base2 = baseline level at end of record

• noisspec = noise spectrum

Kwargs:

• prlen = record length to use (10% pre-max and 90% postmax)

• rotate = rotate pulses to minimum Q [default: False]

• risetime = if True, compute rise time of pulses [default: False]

• bsec = section of record to take for background [default: 0.05] (only used for ‘rotate’ or ‘absolute’)

• absolute = use sqrt(I^2+Q^2) signal [default: False]

• nppos = number of pulse positions to consider for fitting

• shiftpulse = if True, shift pulses to same position for pulse maximum

• flip = flip data in record

• wrtfilter = write the time domain optimal filter to file [ default: False]

• usefilter = use this file for the optimal filter

Returns:

• ifit = fitted pulse heigth parameters

• rtimes = computed rise times of fitted pulses
