There are four options and they are all 15 hours of combined SL and HL with 10 hours of HL only.

The options with Chris' commentary

The beginnings of relativityThe introduction is based around Maxwell's equations rather than Michelson Morley and calculations might involve using the Lorentz transforms on positions and times rather than time dilation and length contraction. Spacetime diagrams are new (and difficult).
Lorentz transformations
Spacetime diagrams
Relativistic mechanics (HL)
General relativity (HL)
EngineeringAll standard stuff. I guess this will be the most popular option as it is by far the most straightforward and ties in nicely with the core. The HL material is not too difficult either.
Rotational dynamics
Fluids (HL)
Resonance (HL)
IntroductionThis is a combination of electromagnetic waves plus communications and medical. The radio telescope is about the only new bit.
Fibre optics (HL)
Medical imaging (HL)
Stellar quantitiesThe astronomy bits like stellar classification and magnitude are not in the course, but I decided to leave a brief explanation of both in my text book as it is difficult to understand stellar data without knowing what the classification means. A bit more depth in the part about CMB.
Stellar characteristics and evolution
Stellar processes (HL)
Further cosmology (HL)
