ctapipe is not stable yet, so expect large and rapid changes to structure and functionality as we explore various design choices before the 1.0 release.

camera_to_shower_coordinates#

ctapipe.image.camera_to_shower_coordinates(x, y, cog_x, cog_y, psi)[source]#

Return longitudinal and transverse coordinates for x and y for a given set of hillas parameters

Parameters:
x: u.Quantity[length]

x coordinate in camera coordinates

y: u.Quantity[length]

y coordinate in camera coordinates

cog_x: u.Quantity[length]

x coordinate of center of gravity

cog_y: u.Quantity[length]

y coordinate of center of gravity

psi: Angle

orientation angle

Returns:
longitudinal: astropy.units.Quantity

longitudinal coordinates (along the shower axis)

transverse: astropy.units.Quantity

transverse coordinates (perpendicular to the shower axis)
