nectarchain.utils.stats.CameraSampleStats#

class CameraSampleStats(shape=(2, 1855, 60), *args, **kwargs)[source]#

Bases: Stats

class CameraSampleStats Accumulator object for Welfords online / parallel variance algorithm, specialized for trace info

Examples

Cumulating the rawdata from a run to get the average waveform:

>>> from nectarchain.utils.stats import CameraSampleStats
>>> from ctapipe_io_nectarcam import NectarCAMEventSource
>>> reader = NectarCAMEventSource(input_url='NectarCAM.Run4560.00??.fits.fz')
>>> s = CameraSampleStats()
>>> for event in reader:
>>>     s.add(event.r0.tel[0].waveform,
>>>           validmask=~evt.mon.tel[0].pixel_status.hardware_failing_pixels )
>>> print(s.mean)
