bad_pix#: list of bad pixels

gain#: default gain value

static make_masked_array(t_peak, window_shift, window_width)[source]#

Define an array that will be used as a mask on the waveforms for the calculation of the integrated amplitude of the signal

Args:: t_peak: sample corresponding the the highest peak of the trace window_shift: number of samples before the peak to integrate charge window_width: duration of the extraction window in samples
Returns:: masked_wfs: a mask array

static subtract_pedestal(wfs, window=20)[source]#

Subtract the pedestal defined as the average of the first samples of each trace

Args:: wfs: raw wavefroms window: number of samples n to calculate the pedestal (default value is 20)
Returns:: wfs_pedsub: wavefroms subtracted from the pedestal

window_shift#: the time in ns before the peak to integrate charge

window_width#: the duration of the extraction window in ns
