CameraCalibrationContainer#

class ctapipe.containers.CameraCalibrationContainer(prefix=None, **fields)[source]#

Storage of camera calibration coefficients for a given time.

Attributes:

timeField(default=0.0): validity time of the camera calibration coefficients.
pedestal_offsetField(default=None): Residual mean pedestal of the waveforms for each pixel. This value is subtracted from the waveforms of each pixel before the pulse extraction. Shape: (n_channels, n_pixels)
factorField(default=None): Multiplicative coefficients for the calibration of extracted charge into physical units (e.g. photoelectrons or photons) for each pixel. The coefficients include the relative correction between pixels to achieve a uniform charge response. Shape: (n_channels, n_pixels)
time_shiftField(default=None): Additive coefficients for the timing correction before charge extraction for each pixel. Shape: (n_channels, n_pixels)
outlier_maskField(default=None): Boolean mask indicating which pixels are considered outliers. Shape: (n_channels, n_pixels)
is_validField(default=False): True if the coefficients are valid, False if they are not valid or if a high fraction of faulty pixels exceeding the pre-defined threshold is detected during the time period.
metadict: dict of attached metadata
prefixstr: Prefix attached to column names when saved to a table or file
