TelescopeFrame

class ctapipe.coordinates.TelescopeFrame(*args, **kwargs)[source]

Bases: astropy.coordinates.baseframe.BaseCoordinateFrame

Telescope coordinate frame.

A Frame using a UnitSphericalRepresentation. This is basically the same as a HorizonCoordinate, but the origin is at the telescope’s pointing direction.

This is used to specify coordinates in the field of view of a telescope that is independent of the optical properties of the telescope.

fov_lon is aligned with azimuth and fov_lat is aligned with altitude of the horizontal coordinate frame as implemented in astropy.coordinates.AltAz.

This is what astropy calls a SkyOffsetCoordinate.

Attributes
