OIF raises an ambiguous spiceypy error when the input objects have any orbital angle which has value >360 degrees. Suggestion would be to add a section to the objectsInField/oif/orbits.py file under def(setOrbits) to "raise ValueError('Orbital angles must be provided within the range [0,360].') for inc, Omega, argPeri and meanAnomaly when checking the input data is valid.
