  The circular Bragg phenomenon is the circular-polarization-state-selective
reflection of light in a spectral regime called the circular Bragg regime. In
continuation of an expository review on this phenomenon published in 2014, an
album of theoretical results is provided in this decadal update. Spectral
variations of intensity-dependent and phase-dependent observable quantities in
the reflection and transmission half-spaces are provided in relation to the
polarization state and the direction of propagation of the incident plane wave.
