- Parameters
- central_obscuration_ratioscalar
The ratio of the central obscuration diameter and the pupil diameter.
- chargeinteger
The charge of the vortex coronagraph used.
- Returns
- scalar
The intensity transmission for a sufficiently off-axis point source for the ring-apodized vortex coronagraph. Point sources close to the vortex singularity will be lower in intensity.
