HillasParametersContainer

class ctapipe.containers.HillasParametersContainer(prefix=None, **fields)

Bases: BaseHillasParametersContainer

Hillas Parameters in a spherical system centered on the pointing position (TelescopeFrame). The cog position is given as offset in longitude and latitude in degree.

Attributes:

intensityField(default=nan)

Total integrated charge (often called ‘size’)

skewnessField(default=nan)

Longitudinal asymmetry of the image

kurtosisField(default=nan)

measure of the longitudinal tailedness of the charges distribution (following Pearson’s definition: equals 3.0 for a normal distribution)

fov_lonField(default=nan deg, unit=deg)

Centroid longitude angle in a spherical system centered on the pointing position

fov_latField(default=nan deg, unit=deg)

Centroid latitude angle in a spherical system centered on the pointing position

rField(default=nan deg, unit=deg)

Radial coordinate of the centroid

phiField(default=nan deg, unit=deg)

Polar coordinate of the centroid

lengthField(default=nan deg, unit=deg)

standard deviation along the major-axis

length_uncertaintyField(default=nan deg, unit=deg)

uncertainty of length

widthField(default=nan deg, unit=deg)

standard spread along the minor-axis

width_uncertaintyField(default=nan deg, unit=deg)

uncertainty of width

psiField(default=nan deg, unit=deg)

Orientation (angle) of major axis relative to X-axis

psi_uncertaintyField(default=nan deg, unit=deg)

uncertainty of psi

transverse_cog_uncertaintyField(default=nan deg, unit=deg)

uncertainty on the centroid along the transverse axis of the image
