Example plot for an lstein plot.
The displayed object is a simulated snii from elasticc.
Different colors denote different passbands.
The $\theta$-axis (angular) shows the passband wavelength.
On the $y$-axis (angular, individual panels i.e., fraction of the entire semicircle plots the brightness in fluxcal).
Finally, in radial direction ($x$-axis) I show time relative to the first recorded datapoint.
