Example of Standard Lomb-Scargle: this example shows how to compute periodicity on from the LINEAR survey, using a standard Lomb-Scargle periodogram and multi-term generalizations.
Example of Multi-band Lomb-Scargle: this example shows how to compute periodicity on multiband data from the SDSS survey, using several variants of the multiband approach from VanderPlas & Ivezic 2015.
