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 intensity (size)

skewnessField(default=nan)

measure of the asymmetry

kurtosisField(default=nan)

measure of the tailedness

fov_lonField(default=nan deg, unit=deg)

longitude angle in a spherical system centered on the pointing position

fov_latField(default=nan deg, unit=deg)

latitude angle in a spherical system centered on the pointing position

rField(default=nan deg, unit=deg)

radial coordinate of centroid

phiField(default=nan deg, unit=deg)

polar coordinate of 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)

rotation angle of ellipse

psi_uncertaintyField(default=nan deg, unit=deg)

uncertainty of psi

transverse_cog_uncertaintyField(default=nan deg, unit=deg)

uncertainty on the center of gravity along the transverse axis of the image
