Adding lightcurve effects to LSST Solar System Simulations
==========================================================

By Jamie Robinson

LSST SSSC Sprint June 2022

This notebook demonstrates the work I did at the Sprint. I wanted to add
changes in asteroid brightness due to rotation and also the longer term
changes of aspect angle that leads to shifts in brightness (on top of
the already modelled distance and phase effects).

The asteroid is modelled as a triaxial ellipsoid rotating around its
shortest axis - axes a > b > c - spin pole orientation (ecliptic
longitude and latitude) - rotation period and simple sinusoidal
lightcurve

This shape model is applied to some asteroid from the simulated
database. The database contains only sparse measurements as expected
from the LSST cadence. Therefore we take the orbital elements and
propagate using `sbpy
open_orb <https://sbpy.readthedocs.io/en/latest/sbpy/data/orbit.html>`__
to densely sample the asteroid positional coordinates.

These positions and and shape parameters are fed into the equations from
`Fernández-Valenzuela 2022 <https://arxiv.org/abs/2202.02374v1>`__ and
so a shift from the expected brightness due to lightcurve effects can be
calculated for any observation made with LSST.

Based on the demo notebook by Juric et al., available from
