Filling non existing members of TelescopePointingContainer
In different places of __init__.py (L263, L264, L378, L379, L493 and L494), the variable pointing of the class TelescopePointingContainer tries to access the members ra and dec. But according to the definition of TelescopePointingContainer (see definition), the only defined members are azimuth and altitude.
Therefore, running ctapipe_io_magic on real MAGIC data will throw an error when trying to access those non existing members.
